摘要
在冷冻条件下用扫描电镜观察了淀粉接枝丙烯酸类高吸水性树脂的结果表明,吸水后的树脂由许多蜂窝状的小室构成,与植物细胞十分相似,本文将这种小室称为水泡。水泡的吸水和失水机理与细胞中的液泡几乎相同。聚合过程应有利于薄而均匀的水泡膜的形成。
The SEM examination of the frozen starch-grafted polyacrylate super water absorbent resin showed that, the water absorbed resin is composed of many honey-comb shaped cells(called“aqua-cells”in this paper),which are much alike to plant cells,mechanism of water absorption and desorption are also nearly same to that of vac- uole in plant cells.Polymerization process should be favorable to the formation of thin and uniform“aqua-cell” membranes.
