Fabrication of SiO2-TiO2/PVDF Copolymer Nanofiber Composite by Electrospinning Process

Multifunctional nanocomposite material is a key material component for the future. It is indicated by many studies have been conducted by researchers in university, research institute and industries. Silicon dioxide (SiO2), titanium dioxide (TiO2) and polyvinilidene fluoride copolymer are very important material due to their excellent properties. In this research paper, we have successfully synthesized SiO2-TiO2/PVDF copolymer nanofiber composite by electrospinning process. SiO2-TiO2/PVDF copolymer nanofiber composite has smooth surface morphology without bead on nanofiber string after confirming by scanning electron microscopy (SEM). Nanofiber composite has average diameter of 350 nm. FTIR and XRD structure analysis of nanofiber composite show us that PVDF copolymer in nanocomposite has a mixed α and β phase crystal structure. Crystal phase of TiO2 in nanofiber composite was in rutile form.
