Abstract
【解決手段】 合成樹脂基材1の片面に極細導電繊維3を含んだ導電層2が形成されたフィルムであって、導電層2が、極細導電繊維が凝集することなく分散して互いに接触しているか、或は、1本ずつ分離した状態で、もしくは、複数本集まって束になったものが1束ずつ分離した状態で分散して互いに接触していて、1.0〜5.0の成形倍率でインモールド成形された後の表面抵抗率が100〜1011Ω/□であるインモールド成形用導電性フィルムとする。
【選択図】 図1
Description
なお、極細導電繊維3は完全に1本ずつ或は1束ずつ分離し分散している必要はなく、一部に絡み合った小さな凝集塊があっても良いが、その大きさは平均径が0.5μm以上でないことが好ましい。
溶媒としてのイソプロピルアルコール/水混合物(混合比3:1)中に単層カーボンナノチューブ(文献Chemical Physics Letters,323(2000)P580−585に基づき合成した物、直径1.3〜1.8nm)と分散剤としてのポリオキシエチレン-ポリオキシプロピレン共重合物を加えて均一に混合、分散させ、単層カーボンナノチューブを0.003質量%、分散剤を0.05質量%含む塗液を調整した。そしてこの塗液を、市販の厚さ100μmのアクリルフィルム(鐘淵化学工業株式会社製SD014NRT、全光線透過率94.0%、ヘーズ0.6%)の片側の表面に塗布することにより導電層を形成し、本発明のインモールド成形用導電性フィルムを得た。
溶剤としてのシクロヘキサノンに、熱可塑性樹脂として塩化ビニル樹脂の粉末を1.7質量%添加して溶解した。この溶液中に単層カーボンナノチューブ(カーボンナノテクノロジーズ社製、直径0.7〜2nm)と分散剤としての酸性ポリマーのアルキルアンモニウム塩溶液を加えて均一に混合、分散させ、カーボンナノチューブを0.3質量%、分散剤を0.18質量%含む塗液を調整した。この塗液を実施例1で用いたのと同じ市販の厚さ100μmのアクリルフィルムの片側の表面に塗布することにより導電層を形成し、本発明のインモールド成形用導電性フィルムを得た。
