摘　　要：目前流体在纳微尺度下的化学非均一表面上表现出的优异性能已引起普遍关注,但是如何使其在化工中得以应用成为化学工程师们面临的难题之一。本文在分析了化学非均一表面在化工应用中已表现出优异性能的基础上,从化学非均一表面的润湿行为和受限空间下化学非均一对分子传递的影响两方面综述了其研究进展。认为化学非均一表面的表面性质受到诸多因素影响非常复杂,但利用现代表面技术和分子模拟的手段,可从微观、分子层面研究流体在化学非均一表面的作用机理,进而可改善和提高诸多化工过程,是推动现代化工发展的重要途径之一。The demonstrated excellent performance of fluid on the nano-/microscopic chemical heterogeneous surface has attracted wide attention. However, the application of the chemical heterogeneous surface in chemical engineering is still a baffling issue to chemical engineers. In this article, the distinct properties of heterogeneous surfaces in chemical industry are discussed, and based on recent publications, the wetting behavior on heterogeneous surfaces and the influences of chemical heterogeneity on molecular transport are reviewed. The factors affecting the properties of chemical heterogeneous surfaces are complicated. With the method of modern surface science and computer technology, and based on the understanding of interaction of fluid and surface on the molecular level, most chemical processes could be improved. Thus chemical heterogeneity could be considered one of the methods promoting the development of chemical industry.
