摘要：
A composite material is formed by combining an expandable polymer having a charge with another polymer having an opposite charge to produce. In particular, the composite material can be prepared by combining the polymers with a medium such as and water, and expanding the mixture using a treatment that expands the mixture to produce, for example, insoluble porous foam-like composite
