The purpose of the paper is to obtain a new composite material based on chemically functionalized nanoparticles dispersed in plastomer matrix. The dispersion of the ZnO nanoparticles in a plastomer matrix (PETr) leads to a high-performance polymeric material with multi-functional, antibacterial, and plastomer-specific processing properties. In this paper, elastomeric nanocompound materials were selected, due to performance properties such as: antimicrobial, resistance to aggressive chemical agents, mechanical properties, especially hardness which, depending on the degree of plastification, can present values from very low to high 30 -100°Sh D, thermal, impermeability, resilience, low density, elasticity, thermostability, processability, impact resistance etc. Nanocomposites were obtained by state-of-the-art technology, specific to nanostructure, in continuous flow, without emissions and waste release in the environment, and with optimal technical parameters, technology that can be integrated in the industrial lines specific to the polymer sector. ZnO functionalization is achieved with polydimethisiloxane (PDMS) and morphological characterized by SEM, DSC/TG, and X-ray diffraction. PETr is mixed with different concentrations of functionalized nanoparticles. The characterization of antibacterial polymeric nanocomposites with PETr matrices and nanoZnO was carried out by FTIR spectroscopy. The physical-mechanical tests, hardness, density, tensile strength, abrasion, melt flow index, etc., were carried out according to the standards in force. The influence of ZnO and its functionalization was studied by comparing the rheological and physical-mechanical properties obtained for the new nanocomposites.
