Abstract
AbstractShape memory epoxy (SMEP) is a high performance shape memory polymer; however, is extremely flammable which severely restricts its applications. In this work, a novel polydopamine modified ammonium polyphosphate (PDA@APP) flame retardant was prepared to improve the flame retardant and enrich the response method of SMEP. Through flame retardancy test confirmed that the flame retarding properties of the PDA@APP/WEP composites significantly improved than the APP/WEP composites, the limiting oxygen index (LOI) values of the APP/SMEP and the PDA@APP/SMEP samples increased by 29.8% and 32.2%, respectively. Moreover, the PDA@APP/WEP composites had excellent light response shape‐memory performance. Interestingly, the PDA@APP/WEP treated polyester fabric exhibited excellent light crease recovery performance and excellent flame retardant property. This work develops a new method for fabric crease recovery and will help broaden the application of WEP and its composites.
