제목 Electrical Property of Polyvinyldene-fluoride-CNT Nanocomposite Film by Spray coating
초록 β Polyvinyldene fluoride (PVDF), a typical polymer ferroelectrics, has been widely studied due to its high dielectric constant, superior piezo and electrocaloric effect compared with other polymer. PVDF have been found up to now four different crystal structures: α-phase; β-phase; γ-phase; δ-phase. Because of the significant piezoelectric property in β-phase PVDF film, the β-phase of PVDF film is very important at the application of actuator. Therefore, the researches to make the β-phase have been carried out. The β-phase PVDF film was usually fabricated by stretching along the length direction or poling process.

 In this work, the PVDF films were fabricated by Spray-coating method. A carbon nanotube (CNT) was included as additive into the PVDF solution for the improved electrical property. And, Dimethylformanmide (DMF) was used as a dispersant of CNT because of the difficulty of mixing. For comparison,  the PVDF films were fabricated other coating process. Consequentially, the electrical properties were enhanced by adding CNT.
