Biodegradable nanocomposites of c ellulose acetate phthalate and c hitosan reinforced with functionalized nanoclay (NC) were prepared. The NC loading was varied from 0 to 10%. The mechanical and thermal properties have been investigated for these composites. The nanocomposites exhibited enhanced mechanical properties due to the addition of NC . The scanning electron micrographs of the blend specimens also support the above observations. Thermogravimetric analyses were carried out to assess the degradation stability of the blends. The blend shows an increase in the rate of biodegradation and water uptake with higher loading of NC . The exfoliation of NC was analyzed by X‐ r ay diffraction studies. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2012
