Nanomaterials TiO 2 have been synthesized by the co-precipitation method using T1CI3 precursor and obtained TiO 2 powder with the crystal morphology of nanoparticles and nanorods. TiO 2/PMMA bilayer film has been prepared by a spin-coating method, with the first layer used PMMA layer for anti-reflection function and microscope slide glass (MSG) is used as a substrate. The optical properties of TiO 2 layers are measured on a single layer with the variation of the spin rate of the spin coater by measuring the absorption as a function of wavelength with used the spectrometers UV-Vis. The TiO 2 layer is deposited from a TiO 2 solution prepared by mixing TiO 2 powder, a binder of ethyl cellulose, and solvent of terpineol with a mass ratio of 1: 1: 28. The antireflection coating properties of TiO 2/PMMA bilayer have been investigated by using transmittance measurement.
