影响膜的成膜过程不仅仅是凝胶浴的组成,其温度以及膜液的组成都将对膜的形态、结构产生影响。在AFM的帮助下,通过对表面形态的观察,了解其成膜机理,以掌握其随条件变化的规律,制备出性能良好的膜。
3.AFM的应用前景
AFM在膜技术方面显示了强大的应用能力。无论在空气中或是液体环境中,AFM无需对膜进行任何可能破坏表面结构的预处理,就能生成高清晰度的膜表面图象。通过对膜表面形态、结构以及与颗粒间的相互作用力进行测定,使人们掌握膜的结构、形态与膜性能之间的关系,了解膜的抗污染程度,以及对成膜机理进行更深入的研究,推动膜科学技术的迅猛发展。
AFM是一项新技术,随着其不断地发展,在膜技术方面的应用将不断地被开发出来,而具有广泛的应用前景。
