Boosting fire safety and mechanical performance of thermoplastic polyurethane by the face-to-face two-dimensional phosphorene/MXene architecture
文献摘要：
Black phosphorus(BP),as one of the most promising fillers for flame retarding polymer,has been seri-ously limited in practical application,due to the agglomeration and poor structural stability challenges.Here,the BP was modified by MXene and polydopamine(PDA)via ultrasonication and dopamine mod-ification strategy to improve the structural stability and dispersibility in the matrix.Then,the obtained(BP-MXene@PDA)nanohybrid was employed to promote the mechanical performance,thermal stability,and flame retardancy of thermoplastic polyurethane elastomer(TPU).The resultant TPU composite con-taining 2 wt.％of BP1-MXene2@PDA showed a 19.2％improvement in the tensile strength and a 13.8％increase in the elongation at break compared to those of the pure TPU.The thermogravimetric analysis suggested that BP-MXene@PDA clearly enhances the thermal stability of TPU composites.Furthermore,the introduction of the BP-MXene@PDA nanohybrids could considerably improve the flame retardancy of TPU composite,i.e.,64.2％and 27.3％decrease in peak heat release rate and total heat release,respec-tively.The flame-retardant mechanisms of TPU/BP-MXene@PDA in the gas phase and condensed phase were investigated systematically.This work provides a novel strategy to simultaneously enhance the fire safety and mechanical properties of TPU,thus expanding its industrial applications.
