Enhancement of chromic-piezoelectric sensitivity responses of polyvinylidene fluoride/polydiacetylene nanofibers using graphene oxide

The composite nanofiber of polyvinylidene fluoride (PVDF)/polydiacetylene (PDA) is one of the chromic and piezoelectric sensors. In this research, we investigated the effect of adding graphene oxide (GO) nanoparticle to this composite on chromic and piezoelectric properties of the PVDF/PDA/GO. We have also examined the mechanical properties of the PVDF/PDA/GO composite. 5 nanofiber samples with 23%w/v PVDF concentration and 1/3 diacetylene with...
