摘　　要：以聚乙烯醇为粘结剂,氧化铝为无机材料,采用真空吸附的方法制备了聚乙烯醇-氧化铝隔膜,并研究了聚乙烯醇的质量、氯化钠的质量、反应温度和反应时间分别对聚乙烯醇-氧化铝隔膜的电阻、气密性能和结构的影响。研究发现,原料配比和反应温度对聚乙烯醇-氧化铝隔膜的电化学性能有着重要影响,反应时间在超过6 h后对聚乙烯醇-氧化铝隔膜的电化学性能基本上无影响,并通过扫描电镜对隔膜的微观形貌进行了表征。According to the vacuum adsorb method,the polyvinyl alcohol-alumina diaphragm was synthesized with polyvinyl alcohol and alumina,and the infection of the quality of polyvinyl alcohol,the quality of sodium chloride,reaction temperature and reaction time to the diaphragm resistance,gas-tightness and structure was also studied.The study found that raw material ratio and reaction temperature had an important influence to the electrochemistry performance of polyvinyl alcohol-alumina diaphragm,reaction time was more than six hours had no influence to the electrochemistry performance of polyvinyl alcohol-alumina diaphragm.What is more,besides microstructure of polyvinyl alcohol-alumina diaphragm was investigated by SEM.
