▎ 摘　　要

The key factors in the design of nanocomposites include obtaining a good adhesion between components and homogeneous dispersion of the nanoadditive in the polymer matrix. Direct mixing of graphene with polymers which are then processed by melt compounding method results in strong tendency of nanoadditive to agglomerate. The article presents a new approach to obtaining poly(vinylidene fluoride)/graphene (PVDF/rGO) nanocomposites in the form of fibers. This method is characterized by the use of graphene oxide (GO) dispersed in the plasticizer instead of graphene. The combination of the fibers forming process with simultaneous reduction of GO to rGO allowed the authors to obtain nanocomposites with graphene homogeneously dispersed in the polymer matrix. Moreover, addition of graphene resulted in formation of beta-phase in the nanocomposites, which is characteristic for PVDF and responsible for pyroelectric and piezoelectric properties of this polymer.
