技术领域technical field
本发明属于溶液聚合技术领域,涉及一种光引发的高分子聚合物及其制备方法。The invention belongs to the technical field of solution polymerization, and relates to a photoinitiated high molecular polymer and a preparation method thereof.
背景技术Background technique
光聚合是一种十分常用的技术,通常可分为光直接引发聚合,或光通过光引发剂引发聚合。丙烯酸树脂在紫外光照射下固化就属于前者,后者往往需要特定的光引发剂。而光引发剂通常难以合成或成本很高,而且多为消耗品。因此需要发展出其他的途径来实现光聚合。Photopolymerization is a very commonly used technique, which can usually be divided into direct photopolymerization or photopolymerization via photoinitiators. The curing of acrylic resin under ultraviolet light belongs to the former, and the latter often requires a specific photoinitiator. However, photoinitiators are usually difficult or expensive to synthesize, and most of them are consumables. Therefore, it is necessary to develop other ways to achieve photopolymerization.
荧光素类与罗丹明类都属于十分常见的荧光物质,经常被用于生物切片的染色。相对于传统光引发剂而言,二者使用可见光、日光进行聚合,这毫无疑问会极大地改善施工条件,减少紫外光对于人体的伤害。另外一方面,荧光素与罗丹明都易于溶解在水中、甲醇中,在聚合反应之后可以轻易的通过多次沉淀溶解的方法除净光催化剂本身的颜色,更不会产生其他光引发聚合中泛黄现象。Both fluoresceins and rhodamines are very common fluorescent substances and are often used for staining biological sections. Compared with traditional photoinitiators, the two use visible light and sunlight for polymerization, which will undoubtedly greatly improve the construction conditions and reduce the harm of ultraviolet light to the human body. On the other hand, both fluorescein and rhodamine are easy to dissolve in water and methanol. After the polymerization reaction, the color of the photocatalyst itself can be easily removed by multiple precipitation and dissolution methods, and it will not produce other light-induced polymerization. yellow phenomenon.

本发明的优点和有益效果:Advantages and beneficial effects of the present invention:
1、可见光引发聚合,避免了紫外光对人体的危害,改善施工条件。1. Visible light triggers polymerization, which avoids the harm of ultraviolet light to the human body and improves construction conditions.
2、本发明所描述方法可广泛应用于多种单体、溶剂,具有广泛适用性。2. The method described in the present invention can be widely applied to various monomers and solvents, and has wide applicability.

5、为了克服光引发剂光照易变色等特点。本发明采用廉价易得的荧光物质作为可循环使用的光催化剂代替了光引发剂。荧光素与罗丹明等有机荧光物质分子中含有比较大的共轭体系,这会对光产生比较明显的吸收,吸收光的分子变成激发态,再变回基态的过程中放出荧光。5.

The invention adopts cheap and easy-to-obtain fluorescent substances as recyclable photocatalysts instead of photoinitiators. The molecules of organic fluorescent substances such as fluorescein and rhodamine contain relatively large conjugated systems, which will produce more obvious absorption of light. The molecules that absorb light become excited states, and then emit fluorescence during the process of returning to the ground state.
