Zusammenfassung:Enhancing polymer properties by incorporating organic–inorganic nanoparticles results in improved optical characteristics of the resulting foil nanocomposite. The casting technique was utilized to fabricate foil nanocomposites using three types of neat polymers: PS, PMMA, and PVA, along with three groups of nanoparticles: (Al + ZnO), (Al + Ag), and (Ag + ZnO). Surface characterization of the resulting foil nanocomposite was carried out using AFM, FTIR, and UV–Vis spectroscopy. The RMS surface roughness of PS/(Ag + ZnO) nanocomposite was the lowest at 17.6 nm, while PMMA/(Al + Ag) and PVA/(Al + ZnO) nanocomposites had the lowest roughness at 10.4 and 24.2 nm, respectively. However, the polymer nanocomposites’ average thickness was around 110–120 μm. The nanocomposites’ linear optical parameters, such as optical conductivity, real and imaginary parts of dielectric constants, and extinction coefficient, were investigated and evaluated. All foil nanocomposites exhibited high UV absorption but low Vis absorption, especially when mixed with Ag and Al nanoparticles in the 200–400 nm range. The predicted refractive index values for the resulting nanocomposites exceed 1.5, highlighting the significant impact of incorporating ZnO, Al, and Ag nanoparticles into the polymer matrices. The optical parameters were the highest when incorporating (Ag + ZnO) nanoparticles into the as-mentioned polymer matrices and lowest when incorporating (Al + Ag) nanoparticles into the same polymers. The use of foil nanocomposites paves the way for the future production of high-efficiency optoelectronic devices.
