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.
