Abdelaziz, E. Abdelrazek] Polymethylmethacrylate (PMMA)/silver nitrate (AgNO3) films were fabricated and studied in detail. Complex formation was corroborated using x-ray diffraction (XRD) and Fourier-transfer infrared analysis. The XRD analysis showed that the amorphization of PMMA increases after the incorporation of AgNO3. The thermal and optical properties were studied using differential scanning calorimetry (DSC), thermal gravimetric analysis (TGA), and optical absorption, transmission, and reflection. The DSC thermograms revealed that the glass-transition temperature (T g) is a nonmonotonically decreasing function of AgNO3. The TGA scans showed a decrease in the thermal activation energy (E a) values of PMMA with increasing doping levels. The optical absorption spectra showed a broad band in the wavelength region of 288nm to 481nm for differently doped films, which were assigned to surface plasmon resonance (SPR) of AgNO3 crystallites. The optical transmission (T) and reflection (R) data have been analyzed, and hence the refractive index (n) was determined and discussed. The dopant concentration dependence of SPR, optical band gap (E opt), n, and cutoff wavelength (λ vis) were estimated. It was found that the thermal and optical parameters changed according to the dopant concentration. These changes suggest high sensitivity of these films to doping as candidates for thermal and/or optical sensor applications.
