摘要：
The mapping of chemically heterogeneous regions in PEA/PS film was achieved by reacting the film in a low pH environment and analyzing; by AFM. In 70:30 blend, the domains were identified as PS rich regions and matrix as the PEA rich regions, based on AFM images, FTIR measurements, and chemical modification study. During the course of hydrolysis of PEA, pits were formed in isolated regions of the matrix, as characterized by AFM.
