PVDF/Co3O4 nanocomposite films were prepared by spincoating
technique. Electron microscopy micrographs showed
aggregations of Co3O4 on the polymer surface which affected the
porosity. An increase in magnetization values with increase in
Co3O4 content indicated that the nanoparticles are well incorporated
within the PVDF matrix. A decrease in porosity and
crystallinity was observed with an increase in Co3O4 content. As
a result, PVDF/Co3O4 system showed better conductivity, nearing
the order 10−3 S cm−1, an order of magnitude higher than the blank
PVDF film. These nanocomposite films can be exploited in the field
of energy storage and electrochemical devices.
