在N，N'-亚甲基双丙烯酰胺（MBA）存在下，采用氧化还原聚合法制备了N-异丙烯酰胺（NIPAM）和丙烯酸钠（SA）的水凝胶网络。以这些水凝胶网络为载体，以硼氢化钠为还原剂，原位还原硝酸银，制备了高度稳定、均匀分布的纳米银。实验结果表明，不同粒径银纳米粒子的水凝胶杂化物可以有效地用作抗菌材料。(c) 2006 Elsevier Ltd.版权所有。
Hydrogel networks based on N-isopropylacrylamide (NIPAM) and sodium acrylate (SA) were prepared by redox-polymerization in the presence of N,N'-methylenebisacrylamide (MBA). Highly stable and uniformly distributed silver nanoparticles have been prepared using these hydrogel networks as a carrier via in situ reduction of silver nitrate in the presence of sodium borohydride as a reducing agent. It has been demonstrated that the hydrogel hybrid with different sizes of silver nanoparticles can be effectively employed as antibacterial material. (c) 2006 Elsevier Ltd. All rights reserved.
