摘要：

综述了以Breath Figure(呼吸图案)法制备聚合物及纳米颗粒蜂窝状多孔结构的研究现状.当潮湿的气流吹到聚合物或纳米颗粒的有机溶液表面时,溶剂蒸发导致水微滴在液体表面冷凝重排成六角阵列结构.溶剂和水微滴蒸发完毕后,聚合物或纳米颗粒在基底上形成具有六角阵列的蜂窝状多孔结构.该技术是自组装领域的一大进展,在生物技术、组织工程、微图像技术、高端分离技术、光催化及医药等领域有望获得重要应用.本文系统阐述了规整蜂窝状孔结构材料的构建方法、构建材料、形成机理以及影响因素(包括湿度、浓度、气流方向和速度、溶剂、基底曲率等),评述了蜂窝状多孔薄膜的性质和应用,并对其在化学和材料科学领域的应用前景作了展望.

Abstract:

We reviewed the status of the honeycomb porous structures formed by polymers and nanoparticles via breath figure method. When moist air blows into the surface of polymer or an organic nanoparticles solution on surfaces, the solvent evaporates resulting in water droplets condensed on surface of the liquid and rearrange into hexagonal array. After the solvent and water droplets evaporate completely, the polymer or nanoparticles form into a hexagonal honeycomb structures on substrate. This technology is a major advance in the field of self-assembly, and it is likely to get important applications in the areas of biotechnology, tissue engineering, micro-imaging technology, high-end separation technology and medicine. In this short review we systematically discusses the preparation of regular honeycomb porous structures, the forming materials, formation mechanism and factors (including humidity, concentration, air flow direction and velocity, solvent, base curvature etc.). The properties and application of honeycomb porous films, finally its application in the field of chemistry and materials science is presented.

Key words: honeycomb porous structure, breath figure, surfactant
