纳米自组装薄膜制备及应用研究进展

摘要

With the development of nanotechnology and the application of nanomaterials, different kinds of nanocomposite films should be prepared. In this review, nanoarchitectonics involving films preparation, nano-level material interactions, synergistic effect of external stimuli, and later research progress are summarized. There are three main methods for the preparation of self-assembled thin films:self-assembled monolayer ( SAM) technique, layer-by-layer ( LbL) assembly and Langmuir-Blodgett ( LB) method. Surface nanostructures are prepared effectively and accurately by SAM technology. LbL assembly and LB techniques both provide effective methods for preparing controlled layered nanoarchitectures. Generally, LbL assembly method is commonly used in the preparation of a large area of layered nanostructures. On the other hand, LB technology is mainly used in the preparation process of the unique dynamic interface to achieve the preparation of ultra-thin film.%随着纳米技术的进步,为实现纳米材料各种应用功能,需要制备不同的纳米组装薄膜材料.本文对纳米组装薄膜制备、薄膜制备过程中分子间相互作用、外界刺激下协同作用以及未来发展方向进行了详细综述.在膜纳米结构中,制备薄膜主要有3种方法:自组装单分子膜(SAM)、层层自组装(LbL)以及LB膜技术.SAM技术能够有效、精确地制备表面纳米结构.层层自组装技术及LB技术能够有效地控制并制备层状纳米结构.层层组装方法常用于制备面积较大的层状纳米结构;LB技术主要是利用其制备过程中独特的动态界面实现对超薄膜的制备.
