摘　　要：用光谱方法研究了某些碱性蓄电池隔膜.结果表明:水化纤维素膜、PVA膜和PVA+H_3BO_3膜,浸于碱性溶液中后,发生R—OH+KOH(?)R-O^-+K^++H_2O反应,产生负电荷基团R-O^-.此种基团阻止溶液中Zn(OH)_4^(2-)离子的迁移和锌枝晶生成.这个结果证实了我们以往提出的水化纤维素膜的作用机理.Several alkaline-battery separators have been studied by photo-electron and infra-red spectrum. It is shown that separators of hydrocellulose, PVA, and PVA+HaBOs in alkaline solution produce negative charge group R-O- through reaction R-OH+KOH=R-O+K+ +H2O. These negative charge groups resist migration of Zn(OH)42-ions and formation of zinc dendrite. These results prove the mechanism we presented in the past about the operation of hydrocellulose separator in alkaline storage batteries.
