Environmental friendly and biodegradable nanocomposite (NC) has been developed by efficient intercalation of poly propylene carbonate (PPC) into the interlayer space of cloisite 20B (C-20B) for biomedical and food packaging applications. The physicochemical and structural characterization was studied by X-ray diffraction (XRD) and Fourier transforms infrared spectroscopy. Thermal stability, mechanical property and anti-water sorption capacity of PPC and nanocomposite were scrutinized by thermal gravimetric analysis (TGA), differential scanning calorimeter (DSC), nanoin-dentation analyzer and thin film diffusion analyzer, respectively. Nanocomposite showed very high thermal decomposition temperature (Td50%) and 10 °C higher glass transition temperature when compared to pure PPC. In addition the nano-composite exposes high elastic modulus, hardness and anti-water sorption property as compared to PPC. Therefore, this nanocomposite can be used in biomedical and food packaging applications.
