功能性聚乙烯醇基水凝胶材料的制备及性能研究
Preparation and characterization of functional polyvinyl alcohol-based hydrogel materials
摘要
Abstract
A modified polyvinyl alcohol(PVA)material was prepared by grafting the tetraphenylethylene structure with aggregation-induced emission onto the side chain of PVA.The antioxidant monomer containing boric acid structure was copolymerized with a kind of water-soluble monomer,and a water-soluble antioxidant polymer was made.After the physical mix of these two water-soluble polymers,a self-healing hydrogel system based on dynamic borate ester bonds were constructed,and this system demonstrated intrinsic aggregation-induced emission and antioxidant properties.The microstructure,fluorescence,mechanical,and antioxidant properties of the hydrogel were investigated by FTIR,1H NMR,and SEM.The experimental results showed that the two water-soluble polymer materials can form injectable hydrogels quickly through dynamic borate ester bonds,and the hydrogels also exhibited their aggregation-induced emission and antioxidant properties,which are expected to be applied in fluorescence sensing,drug controlled release and other fields.关键词
