定向介孔薄膜是指内部孔道沿着同一方向定向排列的介孔薄膜.本文就定向介孔薄膜的制备方法特别是近几年内的进展进行了回顾和评述,按形成介孔薄膜的机理总结出三类制备介孔薄膜的方法,并且分析了薄膜制备过程中的影响因素,从薄膜定向性的角度对制备介孔薄膜的研究进行了分析与展望,提出了今后制备定向介孔薄膜的发展方向和研究热点.
The film containing oriented mesochannels in uniform direction at large scales can be defined as ordered mesoporous thin film. Various preparation methods of ordered mesoporous silica thin films are reviewed in recent years. These preparation methods can be summarized into three kinds in mechanism. The factors influencing the mesoporons film preparation are also discussed and analyzed based on the viewpoint of “order”. In addition, the progress tendencies of those preparation methods in the future are also introduced.
