摘　　要：通过水溶液聚合方法,制备出含银的醋酸钾/聚丙烯酰胺和醋酸钾/聚丙烯酸钠-丙烯酰胺复合调湿抗菌材料,并对材料的表面形貌、结构、吸放湿和抗菌性能进行了研究。试验结果表明,复合调湿抗菌材料呈细小、分散的颗粒状。与聚丙烯酰胺、聚丙烯酸钠-丙烯酰胺单一高分子材料相比,醋酸钾/聚丙烯酰胺、醋酸钾/聚丙烯酸钠-丙烯酰胺复合材料不仅具有较大的吸放湿容量和吸放湿速度,而且对大肠杆菌和藤黄微球菌具有较好的抑菌效果,抑菌率均在90%以上。Potassium acetate/polyacrylamide （ CH3 COOK/PAM） and potassium acetate/poly （ sodium acrylate- acrylamide） （CH3COOK/PAAS-AM） composite materials modified by silver ions were synthesized by water solution polymerization methods, and then the surface morphology, structure, humidity controlling and antibacterial behaviors of CH3COOK/PAM and CH3COOK/PAAS-AM composite were analyzed and determined. The results show that the prepared composite is in fine and discrete particle. Compared with polyacrylamide and poly （ sodium acrylate-acrylamide） materials, CH3 COOK/PAM and CH3 COOK/PAAS-AM composite have greater capacity and faster humidity absorption and desorption. By using E Coli and Micrococcus Luteus as detective bacteria, CH3COOK/PAM and CH3 COOK/PAAS-AM composite have better antibacterial effect with the antibacterial rate above 90%.
