摘要：

Honeycomb-patterned porous biodegradable PLA film can be successfully prepared by the Breath Figure (BF) method, which is a self-assembly template and low-cost process. In this research, the fabrication was designed to create a convenient and simple process aimed at meeting commercial requirements. Production of regularly ordered pattern microporous film is carried out in a closed system with optimum conditions. Thus, important production factors -that is, the starting polymer concentration in solution, the type of solvent (which affects the solvent evaporation rate), and the relative humidity of the closed chamber -were investigated to identify the optimum conditions. The results showed that highly ordered porous film with smaller average pore size of 23.29 +/- 4.55 mu m on strut was generated (19.98 +/- 2.82 mu m) when high PLA concentration (10% wt PLA) in dichloromethane with 80-85% RH relative humidity was applied.
