Abstract

Abstract:

A porous poly(lactic acid) film with a well-ordered honeycomb structure was prepared via the breath-figure method. The addition of amphiphilic Pluronics® was proved to be able to benefit a lot to fabricate the well-ordered honeycomb-patterned film. Several influencing factors including atmosphere humidity, solution concentration and the molecular weight were investigated. The fluorescein isothiocyanate labelled bovine serum albumin(FITC-BSA) was used as the probes to investigate the protein absorption onto the pattern film. Fluorescence images showed the corresponding honeycomb patterns, indicating that the honeycomb-patterned films with protein-resistant pores could be successfully constructed with Pluronics® as the second component.

Key words: Water-assisted fabrication, Honeycomb structure, Poly(lactic acid), PEO-PPO-PEO
