醋酸钾/聚丙烯酰胺类复合材料的制备与调湿抗菌性能

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。

Abstract： Potassium acetate/polyacrylamide(CH_3COOK/PAM) and potassium acetate/poly(sodium acrylate-acrylamide)(CH_3COOK/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 CH_3COOK/PAM and CH_3COOK/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,CH_3COOK/PAM and CH_3COOK/PAAS-AM composite have greater capacity and faster humidity absorption and desorption.By using E Coli and Micrococcus Luteus as detective bacteria,CH_3COOK/PAM and CH_3COOK/PAAS-AM composite have better antibacterial effect with the antibacterial rate above 90%.
