摘要:

基于介孔薄膜的有序納米孔結構及一致孔徑，通過客體組分的高效負載，開展介孔基納米復合薄膜的制備科學與性能研究是近年來材料、化學、物理領域的共同熱點。本文首先綜述了國內外近年來在介孔薄膜及介孔基納米復合薄膜方面的工作進展，重點闡釋了通過模板置換、離子交換、有機硅烷表面修飾等新方法設計，以及在介孔薄膜中進行金屬氧化物、貴金屬、半導體納米粒子高效負載的研究結果；在此基礎上，進一步綜述了介孔基納米復合薄膜有關非線性光學特性的研究進展，尤其是材料制備過程中的外場環境（磁場、微重力等）對納米復合材料非線性光學性質的可能影響。

Abstract:

Mesoporous materials are the natural micro-reactors for preparation of nanocomposites due to its ordered mesostructures and uniform pore channels. In recent years, through the process design to realize the highly efficient and homogeneous incorporation of guest species, researches on mesoporous-based nanocomposite films have attracted the increasing interests of materials scientists, chemists and physicists. In this review, recent advances on the preparation of mesoporous films and mesoporous-based nanocomposite films are firstly summarized, in which the special attentions are focused on new methodology application, such as template-displacement process, ion-exchange method and organosilane surface-modification protocol, for the incorporation of metal oxide, precious metal and semiconductor nanoparticles in the film matrix. Then, the enhanced non-linear optical (NLO) properties associated with mesoporous-based nanocomposite films are also discussed. More importantly, it is suggested that the possible positive effect of external fields, i.e. magnetic field and microgravity environment, during thermal post-treatment of the mesoporous-based nanocomposite films on their NLO responses.
