[RSC Adv.] Direct functionalization of cellulose nanocrystals with polymer brushes via UV-induced polymerization: access to novel heterogeneous visible-light photocatalysts
关键字：polymer brushes, cellulose nanocrystals, UV-induced photopolymerizations
Cellulose nanocrystals (CNCs) are an exciting class of bio-based materials attracting increasing interest for
a wide range of potential applications due to their nanoscale dimensions, biocompatibility, biodegradability
and large surface area. In this work, we report a universal and facile strategy for the preparation of polymer
brushes on CNCs via photopolymerization in the absence of any initiato...

Surface modification of poly(styrene-b-(ethylene-co-butylene)-b-styrene) elastomer via UV-induced graft polymerization of N-vinyl pyrrolidone
关键字：Styrenic block copolymers, UV-induced graft polymerization, N-vinyl pyrrolidone (NVP), Hemocompatibility
Poly(N-vinyl pyrrolidone) (PNVP) was covalently grafted onto the surface of biomedical poly(styrene-b-(ethylene-co-butylene)-b-styrene) (SEBS) elastomer via a technique of UV-induced graft polymerization combined with plasma pre-treatment. The surface graft polymerization of N-vinyl pyrrolidone (NVP) was confirmed by ATR-FTIR and XPS. Effect of the parameters of graft polymerization, i...

UV 辐照诱导自由基界面共聚制备核-壳型微胶囊
关键字：微胶囊，UV辐照，共聚
近年来，基于微胶囊技术的自修复智能复合材料为延长结构材料的寿命提供了新的技术手段。该领域研究发展迅速 [1-２]，目前多采用脲醛树脂做为壁材的原位聚合法包覆修复剂[３-５]，而利用其他方法制备修复剂胶囊的报道不多。实际上，紫外线聚合方法具有耗能耗时少、环境友好、条件温和且操作简单等特点，但利用UV辐照法制备微胶囊还很少见报道。因此，本文探讨了在O/W乳液中通过UV辐射诱导自由基界面共聚交联制备液芯核壳微胶囊...
