Abstract : the photografting polymerization of n - vinyl pyrrolidone ( nvp ) on the surface of ldpe film with photo grafting method was studied and ldpe - g - nvp was chara cterized by ftir qualitatively
文摘:採用一步法和二步法研究了聚乙烯薄膜表面的n -乙烯基吡咯烷酮光接枝反應，並用傅立葉變換紅外光譜儀定性表徵了反應結果。 -
In the system the effects of photoinitiator and monomer concentration on grafting are not distinct, while photo - reduction time, uv irradiated polymerization time and uv light intensity have more effects on grafting yield
實驗發現，光敏劑濃度對接枝率有一定影響；光還原時間增加，接枝率明顯增加；聚合前期接枝率提高較快，反應後期增加緩慢；紫外光照射強度的改變會影響接枝率。 -
Poor thermal stability as a bottleneck has limited the development of liquid crystal photo - alignment technique. the intrinsic reason is that the photosensitive polymer has large space resistance and decreases the reaction degree of the directional photo - polymerization. the effective solution is focused in the increase of orientational order of photo - alignment film
光控取向技術瓶頸問題是穩定性差，其根本原因是光敏高分子空間位阻太大，定向交聯的反應度太低，有效解決方法應是降低位阻，提高定向交聯度和取向膜分子鏈段的有序度。 -
Polymer dispersed liquid crystal ( pdlc ) films are prepared from photo - polymerization of ( cholesteryl acrylate / 2 - hydroxyethyl methacrylate / liquid crystal ) mixtures induced by ultraviolet radiation
摘要選用丙烯酸膽固醇酯甲基丙烯酸-羥乙酯液晶復合體系，在紫外光照射下制備聚合物分散液晶薄膜。
