摘　　要：通过沉淀法制备Ag/PVA复合水凝胶,对复合水凝胶的微观结构进行了表征,并对其力学性能和抗菌性能进行了研究。结果表明,银微粒可以通过沉淀法均匀分散在水溶性的PVA中,形成Ag/PVA复合水凝胶,并且这种复合水凝胶具有抗菌性能,并改善了PVA水凝胶的力学性能。Ag/PVA hydrogels are prepared by the deposit method, and their structures are also studied by the analysis of SEM, The mechanical properties and the antibacterial properties are investigated in this work, The results show that Ag particles can be dispersed uniformly in PVA, The antibacterial property is obsevved in the hydrogels, and the mechanical properties are maintained.
