Enhancement of dielectric properties of PMMA:TIO₂ nanocomposite for organic field effect transistors / Lyly Nyl Ismail
In this thesis, a composite between poly (methyl methacrylate) (PMMA) with titanium dioxide (TiO₂) films were synthesized, fabricated and characterized using sol-gel spin coating technique. The dielectric, electrical and physical properties of PMMA:TiO₂ nanocomposite films was were investigated, to...
