Shape Memory Polymeric Materials for Biomedical Applications: An Update

Shape memory polymers (SMPs) are emerging smart materials that have the ability to change a shape and revert their permanent on application of external stimulus. SMPs can be divided into four types based shape, elasticity origin, temporary fixing mechanism: chemically cross-linked glassy thermosets, semi-crystalline, physically copolymers, block copolymers. The broad overview recent developments for biomedical applications proves wide applicability in field general medicine, drug delivery, regenerative dentistry, neuromedicine, cancer therapy, orthopedics, corrosion protection. Herein, comprehensive analysis composites with focus types, mechanism, functionality is presented. Relevant technologies future advancement towards also discussed.
