| Abstract: | Shape memory polymers have attracted increasing attention from researchers worldwide. Because of their low cost, remarkable recovery, advantageous mechanical and physical properties, and excellent processing performance, there has been rapid development of these materials in recent years. However, the usage of non-renewable petroleum-based chemicals for the synthesis and manufacture of commercial polymers has caused serious environmental pollution, and biodegradable and renewable materials are urgently requ... |
