Abstract

Organic-inorganic hybrid material based cellulose was synthesized by the sol-gel approach. The explosion of activity in this area in the past decade has made tremendous progress in industry or academic both fundamental understanding of sol-gel process and applications of new functionalized hybrid materials. In this present research work, we focused on cellulose-dopamine functionalized SiO₂/NiO₂ hybrid nanocomposite by sol-gel process. The cellulose-dopamine hybrid nanocomposite was synthesized via λ-aminopropyltriethoxysilane (λ-APTES) coupling agent by in-situ sol-gel process. The chemical structure of cellulose-amine functionalized dopamine bonding to cellulose structure with covalent cross linking hybrids was confirmed by FTIR spectral analysis. The morphological analysis of cellulose-dopamine nanoSiO₂/NiO₂ hybrid nanocomposite materials was characterized by XRD, SEM and TEM. From this different analysis results indicate that the optical transparency, thermal stability, control morphology of cellulose-dopamine-SiO₂/NiO₂ hybrid nanocomposite. Furthermore cellulose-dopamine-SiO₂/NiO₂ hybrid nanocomposite was tested against pathogenic bacteria for antimicrobial activity.
