银氨蒙脱土／聚丙烯酸钠-丙烯酰胺复合材料的制备与调湿抗菌性能

通过插层聚合方法，制备出银氨蒙脱土／聚丙烯酸钠-丙烯酰胺共聚物复合调湿抗菌材料，并对材料的表面形貌、结构、吸放湿和抗菌性能进行了研究．实验结果表明，共聚物复合调湿抗菌材料的结构疏松，表面存在较大孔隙；丙烯酸．丙烯酰胺分子单体经插层聚合成功地引入到蒙脱土层间，层间距扩大为2．143nm．与聚丙烯酰胺、银氨蒙脱土／聚丙烯酰胺材料相比，银氨蒙脱土／聚丙烯酸钠-丙烯酰胺共聚物复合材料具有较高的吸放湿容量和吸放湿速度；且对大肠杆菌和藤黄微球菌具有较强的抑菌效果，抑菌率均在90％以上．

Synthesis, Humidity Controlling and Antibacterial Behaviors of [Ag(NH3)2]+Modified Montmorillonite / Polysodium Acrylate-Acrylamide Composite

Ag（NH3）2]^＋ modified montmorillonite/polysodium acrylate-acrylamide （sMMT/copolymer）composite was synthesized by water solution intercalation and polymerization methods, and then the surface morphology, structure, humidity controlling and antibacterial behaviors of sMMT/copolymer composite were analyzed. The results show that the sMMT/ copolymer composite is loose and porous on surface. The acrylate-acrylamide monomer is successfully intercalated into the layers of montmorillonite,and the distance between two layers is increased to 2.143 nm. Compared with polyacrylamide （PAM） ,montmorillonite/polyacrylamide （sMMT/PAM） composite,the as-prepared sMMT/copolymer composite has a greater capacity and higher speed of humidity absorption and desorption. By using E Coli and Micrococcus Luteus as detective bacteria, sMMT/copolymer composite has a very good antibacterial effect with the antibacterial rate above 90%.
