Graphene oxide-based materials are well known for their electrical properties. Novel ternary composite films (PVDF-GO-FK-31) were prepared by introducing a metal complex, for the first time, in a graphene oxide-PVDF polymer matrix (where PVDF = polyvinylidene fluoride; GO = graphene oxide; FK-31 = [Ni(PPh3)2(SCOf)2] (SCOf = furan-2-thiocarboxylate). In these composites, the graphene oxides show strong interfacial bonding with the PVDF matrix due to the incorporation of the FK-31 molecules. The experimental results showed that the incorporation of FK-31 into the PVDF-GO matrix greatly improved the dielectric constant and suppressed dielectric loss values. The composites thus may be used as dielectric materials for electronic capacitors.
Graphical Abstract
For the first time, a ternary composite was prepared by incorporating a newly synthesized square planar nickel(II) complex in a graphene oxide-PVDF polymer matrix and its dielectric and electric properties were studied. With increasing concentration of the complex in the ternary composite its dielectric constant and electrical conductivity increases while the dielectric loss decreases.
期刊介绍：
Journal of Chemical Sciences is a monthly journal published by the Indian Academy of Sciences. It formed part of the original Proceedings of the Indian Academy of Sciences – Part A, started by the Nobel Laureate Prof C V Raman in 1934, that was split in 1978 into three separate journals. It was renamed as Journal of Chemical Sciences in 2004. The journal publishes original research articles and rapid communications, covering all areas of chemical sciences. A significant feature of the journal is its special issues, brought out from time to time, devoted to conference symposia/proceedings in frontier areas of the subject, held not only in India but also in other countries.
