Assistant effect of poly(methyl methacrylate)-grafted carbon nanotubes on the beta polymorph of poly(vinylidene fluoride) during microinjection

Poly(vinylidene fluoride) (PVDF) with numerous electroactive beta crystals was obtained via melt-processing under the coupled effects of an external flow field generated by microinjection and by dipole-dipole interaction with poly(methyl methacrylate)-grafted carbon nanotubes, which represents a significant route for expanding the potential applications of piezoelectric PVDF devices.
