Polyvinylpyrrolidone matrix concentration effects on the physical properties of TiO2 nanofibers prepared using electrospinning method

Polymer plays vital role in assisting fibers (micro or nano) formation via electrospinning method. In this study polyvinylpyrrolidone (PVP) was used and the concentration of the polymer was manipulated by varying its weight percent in the sol-gel solution.

Description
Summary:Polymer plays vital role in assisting fibers (micro or nano) formation via electrospinning method. In this study polyvinylpyrrolidone (PVP) was used and the concentration of the polymer was manipulated by varying its weight percent in the sol-gel solution. From the images obtained, it was observed that solution with low polymer concentration produced few but very small fibers. Increasing the polymer concentration in the sol-gel solution resulted in larger number of fibers being formed but it also increases the fibers diameter size. In term of roughness, sample with 12.5 wt% PVP has coarser surface of 327 nm while sample with 2.5 wt% has smoother surface of 22.559 nm.
