Biomimetic Aligned Porous Materials Made from Natural Biopolymers by UFDM

摘要

Unidirectional freeze-drying method has been tried to prepare biomimetic aligned porous materials (APM) from natural macromolecules such as chitosan,gelatin,alginate,carrageenan,various starches,and their composites.All the porous materials have high porosity and surface area,although the pore morphology varies for different sources of natural macromolecules,composition and concentration of solution,as well as crosslinking degree.The APM has potential applications in bioseparation,biomedical engineering,tissue engineering,food and environmental protection.
