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
