采用一步还原法和螯合法制备Ag/PAN纳米纤维膜。采用SEM,UV,XRD,FT-IR傅里叶变换红外光谱仪对该纤维形貌,银粒子晶型、尺寸、官能团进行表征。得知两种方法都可制备出嵌有(或附着)纳米银颗粒的PAN纳米纤维膜,银粒子的粒径可以达10nm,且经过比较,Ag/PAN膜经过还原处理后,表面Ag粒子的含量更高,分布更均匀。 Ag / PAN nanofibrous membranes were prepared by one-step reduction and chelation. The fiber morphology, silver particle crystal form, size and functional group were characterized by SEM, UV, XRD and FT-IR FT-IR. It is known that PAN nanofibers embedded with (or attached to) silver nanoparticles can be prepared by both methods. The size of the silver particles can reach 10 nm. After the reduction of the Ag / PAN film, the Ag nanoparticles on the surface Higher content, distribution more evenly.
