摘要

界面诱导相分离是由界面润湿效应所诱发的共混体系非平衡相变现象。本文评述了相分离体系薄膜在界面作用下所表现出来的相形态、相变动力学、润湿层形成机理以及空间维数受限条件下所呈现出来的特殊相结构等。同时着重介绍了针对此现象进行数值模拟的基于Cahn-Hilliard-Cook 方程的理论模型以及相应的模拟研究进展。

Abstract

Surface-directed phase separation (SDPS) is a nonequilibrium phase transition of mixtures induced by the wetting behavior of the surface.In this paper

the phase morphologies

evolution dynamics

wetting layer formation mechanisms in SDPS and the novel phase structures of SDPS under the spatial confinement have been reviewed.The dynamical models for SDPS based on the Cahn- Hilliard-Cook theory as well as the progress for the numerical simulation by using these models have also been introduced.
