Abstract

A hybrid nanocomposite composed of calcium carbonate (CaCO 3) and cellulose acetate (CA) was fabricated by bubbling CO 2 gas into the mixture of CA and Ca(OH) 2 solution. Cellulose acetate-calcium carbonate (CA-CC) nanocomposite was characterized by spectral, thermal and optical methods. FTIR and XRD analysis confirmed the formation of the hybrid nanocomposite and XRD confirmed the formation of CaCO 3 with calcite polymorph. Thermal analysis showed CA-CC nanocomposite has better thermal stability than pristine CA. The CaCO 3 nanoparticles were in sphere shape with 100-1000 nm diameter.
