Outline of Final Research Achievements

Organized microfibrillation is a novel method for printing porosity into polymer films by UV light. Here, we show the formation process of porous structures analyzed by in-situ spectroscopy. As a result, we reveal the does energy dependence of the pore formation speed and structural memory. Based on the formation process study, we create microfluidic devices and their precise control.
