Preparation and characterization of physico-mechanical and structural properties of phthalimide derivative polymeric nanocomposites

In this study, phthalimide derived polymer-TiO2 nanocomposites were prepared by direct mixing method and their mechanical properties compared. The high content filler polymer with sufficient interface bonding the matrix have been to maximize of filler. method, obtained free radical polymerization monomer was mixed TiO2 in weight percentages. pulse-echo used characterize elastic constants through detection ultrasonic waves. Transverse longitudinal velocities calculate Young?s modulus these samples. velocity values showed a linear relationship percentage polymer, which is due strong effective interaction between particles resulting from reinforcing structure. clustering that emerged increase amount reinforcement SEM images became more pronounced it observed pure homogeneously distributed. porosity hardness measurements examined. structure approximately increased as increased. Moreover, TGA results thermal stability linearly ratio comparison polymer.
