Outline of Final Research Achievements

Biodegradable porous film was fabricated using a rod-coil block copolymer consisting of poly(n-hexylisocyanate) (PHIC) and biodegradable polymers as a compatibilizing agent. At first, we prepared polymer alloy films composed of PHIC, biodegradable polymer, and compatibilizing agent. After annealed the film, the film was soaked into hexane to selectively remove PHIC from the film. The prepared film was observed by atomic force microscope (AFM) and confirmed to form pores. The average pore size was about 500 nm and cross sectional analysis showed that the pore persisted from the top surface to the substrate. In addition, biodegradable film having microphase-separated structures with sub-20 nm periodicity was fabricated using block copolymers (BCPs) consisting of maltoheptaose and poly(ε-caprolactone) (PCL).
