The membrane structure and surface features were analyzed by FT-IR and scan electron micrography. 用傅立叶红外光谱和扫描电镜分别测定了膜的结构和表面形貌。
The results show that alkali concentration and treating time have obvious influence on netlike structure.Temperature has small influence on surface topography. 实验结果表明，碱处理时碱液浓度和处理时间对表面形成的网状结构有显著影响，温度对碱液处理后的表面形貌影响不大。
