제목 Ferro-, Piezoelectric properties of Polyvinylidene difluoride(PVDF) - Multiwall Carbon Nanotubes Electrospun Nanocomposite
초록 We prepared poly(vinylidenefluoride)- multiwalled carbon nanotubes composite by using electrospinning process and studied about the additive effect of MWCNT on polymorphic behavior, electroactive properties. FTIR and WAXD reveal that there are dramatic changes in the formation of the β-form crystal structure with the MWCNT loading. It is attributed to nuecleation effect of MWCNT as well as the intense stretching of PVDF jets in electrospinning possess. The value of remnant polarization and piezoelectric response also increase with the MWCNT loading. A further application such as stretching and poling can act as synergistic method to induce not only highly oriented β-form crystallites but also great ferro-, piezoelectric performances.
