Surface and optical properties of nanohybrid PMMA/TiO2 coated glass surface: The effect of molar ratios of PMMA: TiO2 solution

Preparation of nanohybrid PMMA/TiO₂ hybrid was reported by using sol-gel spin-coating method. This studied involve modification optical band gap energy of TiO₂ at different molar concentration of TTIB precursor. Field emission scanning electron microscope (FESEM) results showed TiO₂ particles encapsulate surroundings big size of PMMA particles. This existence of board particles have been confirmed using energy dispersive analysis x-ray (EDAX) spectrum. We have found the atomic force microscopy (AFM) surface morphology result for sample at (1:100) 0.005M precursor molar concentration has matrix of PMMA encapsulated TiO₂ particles. From ultraviolet-visible-near infrared (UV-Vis-NiR) spectroscope, we have found as increase of TTiB precursor molar ratios in PMMA solution, the transmittance properties of nanohybrid PMMA/TiO₂ was increased from 44.24 to 77.39% in visible region. This study suggested for improvement of TiO₂ surface and optical properties coated glass surface.
