ABSTRACT: Researches on the synthesis of bionanocomposite have attracted the attention of scientists owing to their huge potential applications in the field of medical apparels. In the present study, a novel bionanocomposite was synthesized using chitosan and Aloe vera in presence of sodium tripolyphosphate (STPP) as cross linking agent. The structural characterization of synthesized chitosan-Aloe vera bionanocomposite (CABNC) was carried out by analysing UV-Visible, Fourier Transform Infrared (FTIR), Nuclear Magnetic Resonance (NMR) (1H, 13C and 31P) spectra which finally confirmed the composite nature of CABNC. The thermal characterization and surface morphology characterization of obtained composite were conducted on Differential Scanning Calorimetry (DSC), Thermo Gravimetric Analyzer (TGA), Scanning Electron Microscope (SEM) and Atomic Force Microscope (AFM). The results showed higher thermal stability of CABNC as compared to chitosan and Aloe vera alone. Analysis of SEM, AFM and Dynamic Light Scattering (DLS) results indicated rough surface morphology and spherical shape of CABNC particles with average particle diameter of about 48.73 nm.
