摘要：

A hybrid nanocomposite composed of calcium carbonate (CaCO3) and cellulose acetate (CA) was fabricated by bubbling CO2 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. FIR and XRD analysis confirmed the formation of the hybrid nanocomposite and XRD confirmed the formation of CaCO3 with calcite polymorph. Thermal analysis showed CA-CC nanocomposite has better thermal stability than pristine CA. The CaCO3 nanoparticles were in sphere shape with 100-1000 nm diameter. (C) 2011 Elsevier Ltd.
