Study of the properties of MgO/Poly methyl methacrylate Nano-composites

Abstract Nanotechnology applications have recently developed in the field of smart sensors that convert energy from one form to another. is important source renewable applications, such as use solar generate electrical A concentration 0.2 w/v poly methyl meta acrylic dissolved dimethylformamide was prepared using hot plate magnetic stirrer with a temperature up 50 ° C, and mixing continued for an hour. 0.02 Percentage magnesium oxide nanoparticles added (poly methacrylate/dimethylformamide) solution dispersed by ultrasonic dispersion device. The samples were cast into glass containers obtain thin films mm diameter after drying 24 hours. Infrared assays conducted study interactions between polymer via studying nature bonds. differential scanning calorimetry test performed measure thermal properties samples. Atomic force microscopy used surface gap calculated. results proved interaction physical interaction. calorimeter also showed adding MgO leads increase transition small value (80 °C) (82 °C). On other hand, softening point decreases (132 C) (120 melting (173 (135 nanoparticles. As atomic microscopy, it roughness (2.08 nm) (1.7 nanoparticles, while bearing index increases (0.369) (0.582). Also, addition decrease (4.3 – 4.1) eV, which sensitivity.
