Optical and Mechanical Properties of Nanocomposite Films Consist of Polymethyl Methacrylate and Silica Nanoparticles Using Ultrasonic Spray Deposition

In this study, ultrasonic spray deposition (USD) technology was used to prepare nano-composite polymer electrolyte films with polymethyl methacrylate (PMMA) as the matrix, dimethyl carbonate (DMC) as the solvent, and silicon dioxide as the second phase. The annealing procedure improves the uniformity and transmission of the film. Due to the aggregation of fumed silica nanoparticles, the addition of silica reduced the permeability of the electrolyte membrane. However, the addition of the surfactant cetyltrimethylammonium bromide (CTAB) dispersed the nanometer silica particles and returned the optical transmittance of the nanocomposite polymer electrolyte membrane to about 90%. Our nanocomposite polymer electrolyte membranes have better hardness and elastic modulus than commercial materials.
