| Research Abstract |
Cellulose/LiCl/N,N-dimethylacetamide solution and the regenerated cellulose hydro gel prepared from the cellulose solution have been treated by sol-gel processes with alkoxysilanes in order to create cellulose/silica hybrid films to enhance their mechanical properties and thermal stability. The structure and properties of the hybrid films were investigated by X-ray diffraction, SEM, tensile testing, and thermogravimetry. The results revealed that most of the silanes used in this study yielded hybrid films composed of cellulose and silica formed by hydrolysis and condensation reaction of silanes. The tensile strength and thermal stability of the hybrid films were improved over those of the pure regenerated cellulose film. Therefore, this method would show the potential application of developing cellulose-inorganic hybrid materials with high performance.
