(RSC Adv.)Bio–based tetrafunctional crosslink agent from gallic acid and its enhanced soybean oil-based UV-cured coatings with high performance
The utilization of soybean oil-based UV coatings depends on the introduction of petroleum-based comonomers or crosslink agents. Thus, in this paper, a bio-based crosslink agent (GACA) for UV curable coatings was synthesized from gallic acid and its chemical structure was confirmed by FT IR, 1H NMR and 13C NMR. Crosslinked networks with high biobased content of more than 88% were obtained after c...

[RSC Adv.] Direct functionalization of cellulose nanocrystals with polymer brushes via UV-induced polymerization: access to novel heterogeneous visible-light photocatalysts
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...

Thermo- and pH-responsive Behaviors of Aqueous Poly(acrylic acid)/Poly(4-vinylpyridine) Complex Material Characterized by ATR-FTIR and UV-Vis Spectroscopy
A novel thermo- and pH- responsive poly(acrylic acid) (PAA)/poly(4-vinylpyridine) (P4VP) aqueous material with an upper critical solution temperature (UCST) was developed in this study. It was found that the formation of the aqueous complex material was caused by the deprotonation of pyridinium groups of P4VP molecules and consequent hydrogen bonding formation between pyridine and carboxyl...

【Colloids & Surface B】Surface modification of poly(styrene-b-(ethylene-co-butylene)-b-styrene) elastomer via UV-induced graft polymerization of N-vinyl pyrrolidone
Abstract:
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 poly...

紫外辐照对低密度聚乙烯介电性能的影响
关键字：LDPE UV辐照 介电性能
低密度聚乙烯( LDPE)在薄膜消费领域份额占比大，同时挤出成型LDPE在发泡材料和电线电缆料方面的应用逐渐增长；特别是超高压电力电缆绝缘料，其他树脂不能替代LDPE。太阳光中的紫外线被认为是引起高分子“老化”的主要因素，已有报道主要研究聚乙烯等材料光老化过程中表观特征和力学性能的变化，并且利用紫外辐照对其进行增容改性。本工作的内容是研究紫外辐照对LDPE介电性能的影响。热压成型制备系列LDPE膜，在紫外光下辐照不...

关键字：antibacterial, UV-induced graft polymerization, polypropylene nonwoven fabric membrane, hemocompatibility, zwitterionic polymer
In this article, a facile approach to fabricate a biofunctional polypropylene nonwoven fabric membrane (PP NWF) with a switchable surface from antibacterial property to hemocompatibility is presented. In the first step, a cationic carboxybetaine ester monomer, [(2-(methacryboxy) ethyl)]-N,N-dimethylamino-ethylammonium bromide, methyl ester (CABA-1-ester) was synthesized....

Improved biocompatibility and antifouling property of polypropylene non-woven fabric membrane by surface grafting zwitterionic polymer
关键字：Antifouling, Graft polymerization, Polypropylene non-woven fabric membrane, UV-irradiated, Zwitterionic polymer
This work described the graft polymerization of a zwitterionic polymer, [3-(methacryloylamino)propyl]-dimethyl(3-sulfopropyl) ammonium hydroxide (MPDSAH), onto polypropylene non-woven fabric (NWF) membrane via O2 plasma pretreatment and UV-irradiated technique. The surfaces of the modified NWF membranes were principally characterized using attenuated total reflectance Fourier transform i...
