紫外光固化PAA-PAM共聚水凝胶的制备及性能研究
Preparation and properties of UV-curable PAA-PAM copolymer hydrogels
摘要
Abstract
A UV-cured PAA-PAM copolymer hydrogel was synthesized using acrylic acid and acrylamide as monomers,N,N'-methylenebisacrylamide as a crosslinker,and Irgacure™ 2959 as a photo-initiator.The hydrogel properties were comprehensively characterized using FTIR,SEM,mechanical testing,and rheological analysis.This study systematical-ly investigated how glycerol incorporation affects the hydrogel's mechanical strength,viscoelasticity,water retention,ad-hesion,and temperature resistance.Results indicated that glycerol significantly enhanced the hydrogel's performance,im-proving its elongation at break(631.8%),tensile strength(53.0 kPa),adhesion,and extreme temperature tolerance.Optimal properties were achieved with an acrylic acid-to-acrylamide molar ratio of 4∶6,1 ‰ crosslinker concentration,and 60 vol%glycerol content.The developed hydrogel exhibits excellent comprehensive performance,making it promis-ing for various applications requiring flexibility,durability,and environmental adaptability.关键词
