PROCESS CONTROL OF ZINC OXIDE NANO-CRYSTALLINE PREPARED BY A POLYACYLAMIDE-GEL METHOD
摘要
Abstract
Nanosized ZnO powders were synthesized from zinc acetate by a polyacrylamide-gel method. Acrylamide and N,N'-methylenebisacrylamide were used in the synthesis as a monomer, and a network reagent, respectively. The effects of the parameters (such as reactant concentration, content of reaction initiator (NH)2S2O8, pH value of solvent, etc.) on the properties of the nanosized ZnO powders were investigated. The crystalline characteristics of the powders was determined by X-ray diffraction. The results indi-cate that the nanosized ZnO all belong to a hexagonal structure, and the average crystalline grain size decreases with the decreasing of reactant concentration and the reaction initiator content and increasing pH value. In addition, the synthesis process parameters can be optimized at the reaction temperature of 80℃ for 2 h and drying at 100 ℃ for 4 h.关键词
