摘要
以阳离子改性半乳甘露糖(Low Molecular Weight Cationic Guar Gum,LCGG)为亲水性扩链剂,通过自乳化法制备了具有抗菌性能的水性聚氨酯(Waterborne Poly-Urethane,WPU),并系统研究了其理化性质、力学性能及抗菌活性。结果表明:改性后的WPU乳液表现出良好的耐盐稳定性、冻融稳定性和机械稳定性。LCGG增强了胶膜的拉伸强度和粘接性能。对大肠杆菌和金黄色葡萄球菌的抑菌率均达到99%;研究为食品/药品包装领域提供了一种环保、高效的功能性胶黏剂解决方案。
Low molecular weight cationic guar gum(LCGG)was employed as a hydrophilic chain extender to prepare antibacterial water-borne polyurethane(WPU)via a self-emulsification method.The physicochemical properties,mechanical performance,and antibacterial activity of the resulting WPU were systematically investigated.The results demonstrated that the modified WPU emulsion exhibited excellent salt resistance,freeze-thaw stability,and mechanical stability.LCGG enhanced the tensile strength and adhesive performance of the WPU film.Furthermore,the an-tibacterial efficacy of WPU,achieving inhibition rates of 99%against both Escherichia coli and Staphylococcus aureus.This research provides an eco-friendly and high-performance functional adhesive solution for food/pharmaceutical packaging applications.
