Preparation of Poly(Vinylidene Fluoride)/Silica Composite Nanofiber by Electrospinning Technique

Abstract:

A composite nanofiber containing poly (vinylidene fluoride) (PVDF) and silica (SiO₂) were prepared by electrospinning of their mixtrues.The various amount of SiO₂ nanoparticle was add with 15 wt.% PVDF solution in mixed solvent of N,N-dimethylacetamine (DMAc) : acetone at a ratio of 4:6 with the applied voltage of 8 kV, tip to collector distance of 10 cm and flow rate of 1 ml/hr. The morphology of the PVDF/SiO₂ membranes was investigated by scanning electron microscope (SEM). The effect of SiO₂ concentration on the morphology of the composite membranes were discussed. Crystallinity of the composite membranes was investigated by differential scanning calorimetry (DSC). It was found that SiO₂ concentration have significant influence on the morphology and crystallinity of PVDF/SiO₂ membranes.
