The pure polyvinyl acetate (PVAc) nanofiber and PVAc/titanium dioxide (TiO2) composite nanofiber were prepared
by sol–gel process with electrospinning. The effect of increasing TiO2 contents on diameter distribution, surface
morphology, and elastic modulus of nanofibers was characterized using a scanning electron microscope (SEM) and
an atomic force microscope (AFM) equipped with picoforce. SEM images showed that the average diameter of
composite nanofiber decreased with the increase in TiO2 The three-point bending test indicated that the elastic
modulus of PVAc/TiO2 nanofiber significantly increased as TiO2 increased.
