- void layer a porous layer
- the particles are pulverized gel-like compounds.
- a coating film can be formed in the same way.
- the reason why a suitable void structure is formed in the coating film when the particles are pulverized gel-like compounds is presumed to be as follows, for example. However, this assumption does not limit the method of forming the transparent porous film.
- the three-dimensional structure of the gel-like silicon compound before pulverization is in a state where it is dispersed into a three-dimensional basic structure. Furthermore, in the above method, a precursor having a porous structure based on a three-dimensional basic structure is formed by spray coating a crushed product of a gel-like silicon compound onto a base material. That is, according to the above method, a new porous structure (three-dimensional basic structure) different from the three-dimensional structure of the gel-like silicon compound is formed by spray coating the pulverized material. Therefore, the finally obtained transparent porous film can have a low refractive index that functions to the same extent as, for example, an air layer.

- the heating time is not particularly limited as long as the coating film can be sufficiently dried.
- a crosslinking reaction occurs between a plurality of particles included in the coating film. Therefore, the three-dimensional basic structure is fixed. As a result, the finally obtained transparent porous film can maintain sufficient strength and flexibility despite having a structure having voids.
- a transparent porous film is formed on the base material.
- the transparent porous film may be, for example, an open-cell structure with a continuous pore structure.
- An open cell structure means that the pore structure is three-dimensionally connected, and can also be said to be a state in which the internal voids of the pore structure are continuous. Since the transparent porous film has an open cell structure, it is possible to increase the porosity.
- the transparent porous film more preferably has a monolith structure in which the open cell structure includes a plurality of pore distributions.
- the monolith structure means, for example, a hierarchical structure including a structure in which nano-sized fine voids exist and an open cell structure in which the nano-sized voids are assembled. When forming a monolith structure, for example, fine voids provide membrane strength while coarse open voids provide high porosity, making it possible to achieve both membrane strength and high porosity.
- the transparent porous film may preferably be a nanoporous film (specifically, a transparent porous film in which the diameter of 90% or more of the micropores is within the range of 10 ⁇ 1 nm to 10 3 nm).
- the porosity of the transparent porous film is, for example, more than 10 vol%, preferably 20 vol% or more, more preferably 30 vol% or more, even more preferably 35 vol% or more, and, for example, 60 vol% or less, preferably The content is 55% by volume or less, more preferably 50% by volume or less, even more preferably 45% by volume or less.

- the size of the voids (pores) is, for example, 2 nm to 500 nm.
- the size of the voids (pores) is, for example, 2 nm or more, preferably 5 nm or more, more preferably 10 nm or more, and still more preferably 20 nm or more.
- the size of the voids (pores) is, for example, 500 nm or less, preferably 200 nm or less, and more preferably 100 nm or less.
- the size range of the voids (pores) is, for example, 2 nm to 500 nm, preferably 5 nm to 500 nm, more preferably 10 nm to 200 nm, and even more preferably 20 nm to 100 nm.
- the size of the voids (pores) can be adjusted to a desired size depending on the purpose and use.
- the size of voids (pores) can be quantified by the BET test method.
- the size of the voids can be quantified by the BET test method. Specifically, 0.1 g of the sample (formed void layer) was put into the capillary of a specific surface area measurement device (manufactured by Micromeritics: ASAP2020), and then dried under reduced pressure at room temperature for 24 hours to remove the voids. To evacuate gases within the structure. Then, by adsorbing nitrogen gas onto the sample, an adsorption isotherm is drawn and the pore distribution is determined. This allows the void size to be evaluated.

1つの実施形態における透明多孔質形成塗料は、粒子と、粒子が分散される分散媒と、を含んでいる。透明多孔質形成塗料における粒子の濃度は、0.1質量%以上、好ましくは1.0質量%以上、より好ましくは2.0質量%以上であり、6.0質量%以下、好ましくは5.0質量%以下である。分散媒は、150℃以上の沸点を有する第1分散媒を含んでいる。第1分散媒の沸点は、1気圧下における沸点であって、好ましくは155℃以上、より好ましくは165℃以上であり、例えば200℃以下、好ましくは190℃以下である。このような構成によれば、透明多孔質形成塗料における粒子の濃度が上記範囲内であり、かつ、分散媒に含まれる第1分散媒の沸点が上記下限以上であるので、スプレー塗工により透明多孔質形成塗料から透明多孔質フィルムを製造しても、透明多孔質フィルムに優れた透明性を付与でき、かつ、透明多孔質フィルムの表面平滑性を向上できる。
分散媒は、第1分散媒のみからなってもよく、第1分散媒に加えて第2分散媒を含有してもよい。
粒子は、透明多孔質フィルムの製造に適した任意の材料から構成される。粒子を構成する材料としては、例えば、国際公開第2004/113966号、特開2013-254183号公報、特開2012-189802号公報、および、特開2017-25277号公報に記載の材料を採用し得る。当該材料としては、無機物、および、有機物の両方があり得る。
このような材料のなかでは、好ましくは無機物が挙げられ、より好ましくはケイ素化合物が挙げられる。ケイ素化合物の具体的として、シリカ系化合物;加水分解性シラン類、ならびにその部分加水分解物および脱水縮合物;シラノール基を含有するケイ素化合物;ケイ酸塩を酸やイオン交換樹脂に接触させることにより得られる活性シリカが挙げられる。ケイ素化合物のなかでは、好ましくはシラノール基を含有するケイ素化合物が挙げられる。
分散媒は、上記下限以上の沸点を有する第1分散媒を含んでいる。第1分散媒として、例えば、ジメチルスルホキシド(DMSO);エチレングリコールモノエチルエーテルアセテート、エチルラクテートなどのエステル類;ジエチレングリコールエチルメチルエーテル、ジエチレングリコールジメチルエーテル、ジプロピレングリコールジメチルエーテル、ジプロピレングリコールモノメチルエーテル、ジエチレングリコールジエチルエーテル、ジエチレングリコールモノメチルエーテル、ジエチレングリコールブチルメチルエーテル、トリプロピレングリコールジメチルエーテル、トリエチレングリコールジメチルエーテル、ジエチレングリコールモノブチルエーテル、エチレングリコールモノフェニルエーテル、トリエチレングリコールモノメチルエーテル、ジエチレングリコールジブチルエーテル、トリエチレングリコールブチルメチルエーテル、ポリエチレングリコールジメチルエーテル、テトラエチレングリコールジメチルエーテル、ポリエチレングリコールモノメチルエーテルなどのエーテル類;が挙げられる。

次に、本発明の1つの実施形態による透明多孔質形成塗料の製造方法について説明する。透明多孔質形成塗料の製造方法は、親水性媒体中で被粉砕物を粉砕して、粒子が親水性媒体に分散するゾル液を調製する工程と;該ゾル液に含まれる親水性媒体を上記分散媒に置換し、かつ、粒子の濃度を上記範囲に調整する工程と;を含んでいる。このように被粉砕物を粉砕した後に溶媒を置換すると、粒子の分散性を維持できる。
親水性媒体として、例えば、イソプロピルアルコール(IPA)、エタノール、メタノール、ブタノール、アセトン、ジメチルホルムアミド(DMF)、ジメチルスルホキシド(DMSO)が挙げられ、好ましくは、IPAおよびDMSOが挙げられる。親水性媒体は、単独でまたは組み合わせて使用できる。また、親水性媒体は、水と混合されていてもよい。
これによって、上記した粒子の材料から構成される被粉砕物(代表的にはゲル状ケイ素化合物)が調製される。被粉砕物(代表的にはゲル状ケイ素化合物)は、親水性媒体中で、例えば20℃~50℃で、10時間以上熟成される。
これによって、上記した粒子が親水性媒体に分散されたゾル液が調製される。
以上によって、上記粒子および上記分散媒を含む透明多孔質形成塗料が製造される。
上記した透明多孔質形成塗料は、スプレー塗工に好適に採用し得る。スプレー塗工では、上記した透明多孔質形成塗料が、対象物としての基材(代表的には、光学フィルムなど光学部材)に噴霧されて、基材上に塗膜が形成される。基材の形状は、特に制限されない。基材の厚み方向から見た形状として、例えば、矩形などの多角形状;円形状;楕円形状;凹部および/または凸部を有する異形状が挙げられる。また、基材の表面形状も特に制限されない。
1.3≦固形分濃度変化率≦60・・・(1)
(式(1)中、固形分濃度変化率は、スプレー塗工前の透明多孔質形成塗料における固形分濃度に対する、スプレー塗工後10秒時点の塗膜における固形分濃度を示す)。
固形分濃度変化率が上記式(1)を満足すると、透明多孔質フィルムにおける透明性のさらなる向上を図ることができ、かつ、透明多孔質フィルムの厚みムラの低減を図ることができる。
スプレー塗工前の透明多孔質形成塗料における固形分濃度は、例えば0.1質量%以上、好ましくは1.0質量%以上、より好ましくは2.0質量%以上であり、例えば6.0質量%以下、好ましくは3.0質量%以下である。
スプレー塗工後10秒時点の塗膜における固形分濃度は、スプレーヘッドからの塗料の噴霧停止後10秒時点の塗膜における固形分濃度であって、例えば3.7質量%以上、好ましくは4.5質量%であり、例えば6.5質量%以下である。
0.0549e1.2x≦スプレー塗工後10秒時点の塗膜の粘度≦0.0549e3.3x・・・(2)
(式(2)中、eはネイピア数を示し;xはスプレー塗工後10秒時点の塗膜における固形分濃度を示す)。
塗膜の粘度が上記式(2)を満足すると、透明多孔質フィルムの透明性の向上および厚みムラの低減を十分に両立し得る。
1つの実施形態では、当該工程において、塗膜に含まれる複数の粒子間に架橋反応が生じる。そのため、三次元基本構造が固定化される。これによって、最終的に得られる透明多孔質フィルムは、空隙を有する構造であるにもかかわらず、十分な強度と可撓性とを維持することができる。
透明多孔質フィルムは、例えば、孔構造が連続した連泡構造体であり得る。連泡構造体とは、三次元的に孔構造が連なっていることを意味し、孔構造の内部空隙が連続している状態ともいえる。透明多孔質フィルムが連泡構造を有することにより、空隙率を高めることが可能である。透明多孔質フィルムは、より好ましくは、連泡構造が複数の細孔分布を含むモノリス構造を有する。モノリス構造は、例えば、ナノサイズの微細な空隙が存在する構造と、同ナノ空隙が集合した連泡構造とを含む階層構造を意味する。モノリス構造を形成する場合、例えば、微細な空隙で膜強度を付与しつつ、粗大な連泡空隙で高い空隙率を付与し、膜強度と高空隙率とを両立することができる。
透明多孔質フィルムの空隙率は、例えば10体積%を超過し、好ましくは20体積%以上、より好ましくは30体積%以上、さらに好ましくは35体積%以上であり、例えば60体積%以下、好ましくは55体積%以下、より好ましくは50体積%以下、さらに好ましくは45体積%以下である。空隙率がこのような範囲であれば、透明多孔質フィルムの屈折率を適切な範囲とすることができ、かつ、所定の機械的強度を確保することができる。空隙率は、エリプソメーターで測定した屈折率の値から、Lorentz‐Lorenz’s formula(ローレンツ-ローレンツの式)より空隙率を算出された値である。
透明多孔質フィルムを50mm×50mmのサイズにカットし、ヘイズメーター(村上色彩技術研究所社製:HM-150)にセットしてヘイズを測定する。ヘイズ値については、以下の式より算出する。
ヘイズ(%)=[拡散透過率(%)/全光線透過率(%)]×100(%)
各実施例および各比較例で得られた透明多孔質形成塗料と、基材としての無アルカリガラスとを、スプレーコーター(アピロス社製、製品名API-240)にセットした。スプレーヘッド(ノズル)と、無アルカリガラスとの間の距離は、100mmであった。
次いで、霧化圧100kPaおよび塗布量7mL/分の塗工条件にて、透明多孔質形成塗料を無アルカリガラスに対してスプレー塗工した。スプレー塗工の吐出可否を下記の基準で評価した。その結果を表1に示す。
〇:透明多孔質形成塗料の霧化が目視で確認できる。
×:透明多孔質形成塗料の霧化が目視で確認できない。
また、得られた透明多孔質フィルムのヘイズを表1に示す。
(1)ケイ素化合物のゲル化
2.2gのジメチルスルホキシド(DMSO)に、ケイ素化合物の前駆体であるメチルトリメトキシシラン(MTMS)を0.95g溶解させて混合液Aを調製した。この混合液Aに、0.01mol/Lのシュウ酸水溶液を0.5g添加し、室温(23℃)で30分撹拌を行うことでMTMSを加水分解して、トリス(ヒドロキシ)メチルシランを含む混合液Bを生成した。
5.5gのDMSOに、28質量%のアンモニア水0.38g、および純水0.2gを添加した後、さらに、上記混合液Bを追添し、室温(23℃)で15分撹拌することで、トリス(ヒドロキシ)メチルシランのゲル化を行い、ゲル状ケイ素化合物を含む混合液Cを得た。
(2)熟成処理
上記のように調製したゲル状ケイ素化合物を含む混合液Cを、そのまま、40℃で20時間インキュベートして、熟成処理を行った。
(3)粉砕処理
つぎに、上記のように熟成処理したゲル状ケイ素化合物(被粉砕物)を、粉砕処理(高圧メディアレス粉砕)した。粉砕処理(高圧メディアレス粉砕)は、ホモジナイザー(エスエムテー社製、商品名「UH-50」)を使用し、5ccのスクリュー瓶に、混合液D中のゲル状化合物1.85gおよびIPAを1.15g秤量した後、50W、20kHzの条件で2分間の粉砕で行った。
この粉砕処理によって、上記混合液C中のゲル状ケイ素化合物が粉砕されたことにより、混合液Cは、粉砕物(ケイ素化合物の多孔質粒子)のゾル液Dとなった。
次いで、粉砕物のゾル液Dに表1に示す分散媒を添加し、軽く撹拌した後、室温で6時間静置して、ゲル中の分散媒および触媒をデカンテーションした。同様のデカンテーション処理を3回行うことにより、溶媒置換した。
以上によって、透明多孔質形成塗料を得た。当該塗料における粉砕物の濃度(粒子濃度)を表1に示す。当該塗料に含まれる粉砕物の粒度バラツキを示す体積平均粒子径を、動的光散乱式ナノトラック粒度分析計(日機装社製、UPA-EX150型)にて確認したところ、0.50~0.70であった。
