Structural, Thermal, and Rheological Characteristics of PMMA Polymer Doped with ZnO Nanoparticles

Four samples of Poly(methyl methacrylate) (PMMA)dissolved in acetone,(1gm of PMMA and 100ml of acetone) were prepared. Structural, thermal, and rheological characteristics were studied, and zinc oxide nanoparticles (ZnONPs) with concentrations (0.5,1,1.5)wt% were added to PMMA polymer. Structural characteristics after adding different percentages of ZnONPs to PMMA/acetone are found, and the results showed the appearance of new bonds because interaction of ZnONPs with PMMA/acetone. In thermal characteristics, The thermal conductivity values of PMMA/acetone after adding ZnONPs increase with increasing concentrations of ZnONPs. The thermal resistance values of PMMA /acetone decrease with increasing concentration of ZnONPs. In rheological characteristics, the viscosity measurement of PMMA/acetone after adding ZnONPs increases with increasing amounts of ZnONPs. When measuring the density of the PMMA /acetone and comparing it with the density values when adding ZnONPs, we notice a small increase.
