One-pot preparation and applications of self-healing,self-adhesive PAA-PDMS elastomers

论文摘要

A new family of transparent,biocompatible,self-adhesive,and self-healing elastomer has been developed by a convenient and efficient one-pot reaction between poly（acrylic acid）（PAA）and hydroxyl-terminated polydimethylsiloxane（PDMS-OH）.The condensation reaction between PAA and PDMS-OH has been confirmed by attenuated total reflection Fourier transform infrared（ATR-FTIR）spectra.The prepared PAA-PDMS elastomers possess robust mechanical strength and strong adhesiveness to human skin,and they have fast self-healing ability at room temperature（in～10 s with the efficiency of 98%）.Specifically,strain sensors were fabricated by assembling PAA-PDMS as packaging layers and polyetherimide-reduced graphene oxide（PEI-rGO）as strain-sensing layers.The PAA-PDMS/PEI-rGO sensors are stably and reliably responsive to slight physical deformations,and they can be attached onto skin directly to monitor the body’s motions.Meanwhile,strain sensors can self-heal quickly and completely,and they can be reused for the motion detecting after shallowly scratching the surface.This work provides new opportunities to manufacture high performance self-adhesive and self-healing materials.
