Crystalline Structure and Ferroelectric Properties of Poly(vinelidene fluoride)-Chemically Converted Graphene Nanocomposites. |
| 초록 |
Currently, in the field of polymer nanocomposites, intensive attention has been paid to capitalize extreme mechanical, electrical, and thermal properties of graphene. Preferably reduced and unreduced chemically converted graphene(CCG) have beed incorporated into wide variety of polymers to realize applications ranging from electronics to biology-Poly(vinylidene fluoride) (PVDF) was filled with CCG to fabricate bulk films with enhanced thermal and mechanical stability, and electrical conductivity. Until now, the effect of CCG on the crystalline structure and ferroelectric properties of PVDF are not studied, these aspects have been subjected in this work. To facilitate the dispersion in polar solvents, CCG was functionalized with isocyanate groups. Micro-and nano-scale PVDF-CCG composite films were propared by solution casting and spin coating, respectively. Crystalline structure and morphology are being studied. Ferroelectric properties will be assessed by P-E measurements. Acknowledgement : This work was supported by the NRF(R11-2005-065) and the MKE(Grant No.10033449) |
