Study of thermal degradation of PVA/Chitosan/Gelatin electrospun nanofibers

Electrospinning of PVA/Chitosan, PVA/Gelatin, and PVA/Gelatin/Chitosan Blend were prepared to study thermal characteristic by using thermogravimetric analysis (TGA). Electrospinning processes were controlled by applied voltage 16 kVA and tip-to-collector distance (TCD) 0f 14 cm. The morphology and s...

Description
Summary:Electrospinning of PVA/Chitosan, PVA/Gelatin, and PVA/Gelatin/Chitosan Blend were prepared to study thermal characteristic by using thermogravimetric analysis (TGA). Electrospinning processes were controlled by applied voltage 16 kVA and tip-to-collector distance (TCD) 0f 14 cm. The morphology and structure of the fiber were characterized by using scanning electron microscope (SEM) and Fourier transform infrared (FTIR). The influence of PVA addition showed in an image of SEM. Thermal behavior was showed by comparing thin film of PVA/Gelatin/Chitosan Blend in fiber and dip coating. Thermal stability of these samples showed the different melting temperature and phase transition. Fiber sample indicated to begin earlier at melting temperature than dip coating sample.
