用电子显微镜(简称电镜)与光学显微镜相结合的方法,研究了芳香聚酰胺型不对称反渗透膜的形态学。芳香聚酰胺型膜由它的二甲基乙酰胺溶液制备。用玻璃刀将铸膜液在玻璃板上铺展成一定厚度的薄层,在电热板上或烘箱中加热蒸发掉部份溶剂,然后将玻璃板与膜一起浸入凝胶液 The morphology of aromatic polyamide asymmetric reverse osmosis membranes was studied by a combination of electron microscopy (SEM) and optical microscopy. Aromatic polyamide-type membranes are prepared from their dimethylacetamide solution. A glass knife is used to spread the casting solution on the glass plate to form a thin layer with a certain thickness, and a part of the solvent is heated and evaporated on a hot plate or an oven, and then the glass plate and the film are immersed in the gel liquid
