Formation of honeycomb-structured, porous films via breath figures with different polymer architectures

摘要

Honeycomb-structured, porous films with pore sizes ranging from 200 nm to 7 mu m were prepared with breath figures. The regularity of the hexagonal array and the pore size was influenced by the polymer architecture and the casting conditions. A nanoscaled suborder next to the microarray was obtained with amphiphilic block copolymers. These films were shown to be suitable as surfaces for cell growth. (c) 2006 Wiley Periodicals, Inc.
