Abstract

Micro-porous films are fascinating materials of potential applications for membrane filters, micro reactors and so on. Chemical and thermal stabilities of the film are significant for practical applications of these micro-porous films. Recently, the periodic micro-porous structures have been fabricated from a large variety of polymer materials by using condensed water droplet array on the polymer solution as templates. In this report, we show cross-linked honeycomb-patterned films prepared from liquid type oligomers having photo-crosslinkable groups. By controlling the UV irradiation timing, pore size of the well-arranged honeycomb-structures was regulated. After complete cross-linking by annealing, the stable film insoluble to many solvents was obtained.
