The research article presents the investigation of effect of nano filler material on the mechanical and thermal properties of biopolymer. For the preparation of research samples, solvent casting technique was used by dissolving pure polylactic acid (PLA) in chloroform solvent and nanoparticles (Clay) was added to the solution. The mechanical strength, morphology and thermal behavior of the PLA specimens were evaluated by using tensile test, Scanning Electron Microscopy (SEM), Fourier Transform Infrared spectroscopy (FTIR), thermogravimetric Analyzer (TGA), and Differential Scanning calorimetry (DSC). Tensile test shows significant improvement in load carrying capacity and ultimate strength of PLA/nano filler composite. Differential scanning calorimetric analysis shows, decrease in degree of crystallinity of these nanocomposites. Thermogravimetric analyzer (TGA) was used to measure the thermal weight loss of pure PLA and PLA with nano fillers. The Scanning electron micrograph (SEM) shows a good bonding between PLA and nano fillers. The nanoclay interlayer spacing was determined by X-ray diffraction.
