Abstract

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.

纳米杂化PMMA/TiO2镀膜玻璃表面及光学性能:PMMA: TiO2溶液摩尔比的影响

采用溶胶-凝胶旋涂法制备了PMMA/TiO2纳米杂化材料。本研究涉及不同摩尔浓度的TTIB前驱体对TiO2光学带隙能的修饰。场发射扫描电镜(FESEM)结果显示，TiO2颗粒包裹了周围大尺寸的PMMA颗粒。利用能量色散分析x射线(EDAX)光谱证实了板状粒子的存在。我们发现在(1:100)0.005M前驱体摩尔浓度下样品的原子力显微镜(AFM)表面形貌结果有PMMA封装的TiO2颗粒基质。通过紫外-可见-近红外(UV-Vis-NiR)光谱分析，我们发现随着PMMA溶液中TTiB前驱体摩尔比的增加，PMMA/TiO2纳米杂化材料在可见光区的透过率从44.24%提高到77.39%。本研究建议在玻璃表面涂覆二氧化钛以改善其表面和光学性能。
