Preparation and Characterisation of Konjac Glucomannan (KGM)/SiO2 Nanoparticles Blend Film

Abstract:

Article Preview

A novel nanocomposite films was prepared by dispersing SiO2 nanoparticles in aqueous konjac glucomanan (KGM) solution. The structure and miscibility of the nanocomposite materials were determined finely by viscosimetry, Fourier transformed infrared spectra (FTIR), micropolariscope (POM), scanning electron microscopy (SEM) and ultraviolet-visible spectrophotometer (UV-Vis). The results indicated that there was a strong interaction between KGM and SiO2 in ethanolamine. The miscibility and ultraviolet-absorption properties of KGM/SiO2 nanoparticles blend film were improved by ball milling treatment. Moreover, the ultraviolet absorption and tensile strength of the nanocomposite films rapidly increase with the increase of SiO2, while breaking elongation of the nanocomposite films slightly decreased.
