用络合转化法在甲壳胺膜上制备CdS、ZnS纳米微粒

NANOMETER SIZED CdS AND ZnS CLUSTERS PREPARED ON CHITOSAN FILM BY COMPLEX TRANSFORMATION

结构单元上带有配位基团的天然高分子甲壳胺与Ｃｄ２＋和Ｚｎ２＋络合后，通过络合转化方法可以在高分子膜上制备ＣｄＳ、ＺｎＳ等纳米微粒．用这种方法所得微粒尺寸可控、粒径均一、表面缺陷少．

Chitosan, for which ligands within each structural unit can be used as a filmy me dium to prepare the nanometer sized clusters of CdS and ZnS by complex transformation method. The supermicroparticles have been obtained with controlled particle size, uniform distribution of dimension and little crystalline imperfection on the surface.
