ABSTRACT: Chitosan (CH) / Poly (1-vinylpyrrolidone-co-vinyl acetate) (PVP-co-VAc) blend (50:50) [CH/(PVPco-VAc)] strengthened with 2 particle size of TiO2 nanoparticles were ready by resolution casting methodology. Mechanical lastingness, Elongation, Young modulus, Thermal conduction, water absorption, and FTIR analysis were studied for mix and nanocomposites. The tensile results show that the lastingness and Young’s modulus of the nanocomposite films were improved compared with compound mix [CH/ (PVP-co-VAc)] film. The mechanical properties of the compound mix were improved by the addition of TiO2 with important will increase in Young’s modulus (from 2274 MPa to ~2876 MPa) and lastingness (from forty seven.87 MPa to forty nine.65MPa). sturdy surface bonding between the TiO2 nanoparticles and also the [CH/(PVP-co-VAc)], undiversified distribution of the nanoparticles in [CH/ (PVP-co-VAc)] square measure certificatory of markedly improved mechanical strength. The thermal accessibility of the [CH/ (PVP-co-VAc)] mix and [CH/(PVP-coVAc)] /TiO2 nanocomposites films show that it decreased within the adding of nanoparticles TiO2. The solubility calculations demonstrate that the
