Synthesis of cellulose-L-tyrosine –silica hybrid nanocomposites by sol-gel process for high-performance applications

초록

Recently, the great efforts have been made to synthesize one and two dimensional metal nanostructures because of their similar properties. The cellulose is the most abundant biorenewable materials with a long and well established technological base products and important applications such as fiber, paper and membrane polymeric materials. The one dimensional nanomaterials such as nanotubes, nanowires and nanoroads have been widely studied for their potential applications in the field of nanocircuits, nanodevices and nanosensors due to their excellent electronic, optical properties. The properties of the nanomaterials are mainly depends on their sizes and structures of the final materials. In this present work the homogeneous hybrid bio-composites materials such as cellulose-L-tyrosine-silica hybrid materials prepared by in situ sol-gel process using TEOS and γ-aminopropyltriethoxy silane (γ -APTES) as coupling agent. The silica nanomaterials could be attached to the surface of amino functionalized cellulose-L-tyrosine matrices. The covalent bonding behavior of silica were characterized by Fourier transform infrared spectroscopy (FTIR) and morphology was characterized scanning electron microscopy (SEM), X-ray diffraction analysis (XRD) and transmission electron microscopy (TEM).
