Flexible self-healing nanocomposites for recoverable motion sensor

Abstract The recoverable motion sensor with high sensitivity was made based on flexible self-healing nanocomposites. The preparation of these nanocomposites involved incorporating surface-modified CaCu3Ti4O12 (S-CCTO) nanoparticles in self-healing polymer matrix based on dynamic Diels–Alder (DA) adducts. The dependences of electric and dielectric properties of the resultant composites on volume fractions of filler and frequency were investigated. It is found that composites present a high dielectric permittivity of 93 at 100 Hz with 17 vol% filler, approximately 36 times higher than that of pure film. These results agree well with the percolation theory. Furthermore, the hybrid film recovers its capacitance well following a cut and the self-healing process based on DA and retro-DA (r-DA) reaction. We herein show that a polymer matrix based on dynamic DA adducts can be used to make self-healing high-K polymer nanocomposites and recoverable motion sensors. This work may lead to new opportunities for the design and fabrication of various next-generation wearable sensor devices.
