Abstract
Recently, microcellular polymer films have been widely used as absorbents, support cells, and sensors in the industrial fields of IT, NT, BT, and ST. The conventional fabrication methods of microcellular polymer films are not only more complicated than those of non-microcellular polymer films, but also require a longer production time. In this paper, we propose a new hybrid fabrication method for microcellular polymer films; films can be rapidly made using UV laser processing with chemical blowing agents. The experimental results show that the number of the micropores increased with respect to the laser fluence and the concentration of the chemical blowing agents.
