高分子网络凝胶法制备纳米ZnO粉料

PREPARATION OF NANOMETER-SIZED ZINC OXIDE POWDERS BY POLYACRYLAMIDE GEL METHOD

以丙烯酰胺为单体，Ｎ，Ｎ＇－亚甲基双丙烯酰胺为网络剂，用高分子网络凝胶法在低温下制备纳米ＺｎＯ粉体，单体与网络剂的质量比为５∶１粉料的粒度分布为 ５～１５ｎｍ，平均粒径尺寸为８ｎｍ，比表面为１５８．５ｍ２·ｇ－１，ＺｎＯ含量达到９９．０％（质量分数）．

Nanometer-sized ZnO powder was synthesized at low temperature by the polyacry- lamide-gel method. Acrylamide was used as monomer, N,N'-methylenebisacrylamide was used as lattice reagent, and the best mass ratio between monomer and lattice reagent. The particle-diameter distribution of ZnO powder was from 5 to 1.5nm, the average particle size of the ZnO powder was about 8nm and the specific surface area was about 158.5m2g-1. The content of ZnO reached 99.0% (mass fraction).
