Investigations on ZnO/polymer nanocomposite thin film for polymer based devices

Polymer based electronics have recently introduced modern stretchable devices based on polymer technology. Poly methyle mathacrylate is a renowned polymer ordinarily using as photoresist and various other applications. On the other hand, Zinc oxide is famous for its wide band gap semiconducting nature. We are focusing on PMMA-ZnO polymer nanocomposite thin film to excerpt brief properties for its practicability. This nanocomposite thin film is considered an excellent candidate for energy storage applications due to prominent dielectric nature. X-ray diffraction studies confirm the presence of wurtzite ZnO reflections associated with 186-P63mc space group in PMMA-ZnO nanocomposite thin films. Field emission scanning electron microscopy reveals the homogeneous distribution of nanoparticles in PMMA matrix. Optical, photo-catalytic and dielectric measurements display significant increase in photo-catalytic activity, absorption coefficient and dielectric constant in PMMA-ZnO nanocomposite thin film.
