Abstract

Titania have been extremely investigated for employing in the paint fields due to its importance as pigments. Therefore, TiO2 particles are perfect candidates in the paint industry. The nanoparticles were mixed with coating solution (i.e. hybrid sol-gel and organosilicate nanoparticles (OSNP) at concentration (1%wt) for both anatase and rutile. Films were prepared by spin coating method which has been studied by the (Electron Dispersive X-ray Spectroscopy) (EDS)/ (Scanning Electron Microscope) to define the components of concentrations. Results of Raman Spectroscopy to distinguish between crystalline phases, Raman shift resulted for anatase about (142.1, 411.1, 547.4 and 669.6) cm-1 , rutile (190,272,452 and 616) cm-1 . Additionally, the films were studied the thickness and refractive index (n) by Spectroscopic Ellipsometer(SE) for nano-anatase (1%wt) film thickness (128)nm and n equal (2.25), for nano-rutile films thickness (313.5)nm and n equal (2.5). Profilometer investigated the coating topography to demonstrate the Root Mean Square (RMS) to identify the roughness which increased by increasing particle size. Fourier Transform Infrared (FTIR) analysis showed the strong bonds of the nanoparticles in frequency region between (400-1000) cm-1 corresponds to Ti-O-Ti, also the bands at cm-1 were for a symmetric Si-O-Si stretching and vibration, respectively. Self-cleaning tests on the films were performed using Rhodamine B (RhB) as an antioxidant indicator.
摘要纳米溶胶-凝胶复合涂层的制备、拉曼结构特性、形态特征及其在污染罗丹明B (RhB)颜料中的抗氧化应用研究
由于二氧化钛作为颜料的重要性,它在涂料领域的应用受到了极大的研究。因此,TiO2颗粒是涂料行业的完美候选者。将纳米颗粒以1%wt的浓度与锐钛矿和金红石的涂层溶液(即混合溶胶-凝胶和有机硅酸盐纳米颗粒(osp))混合。采用自旋包覆法制备了膜,并用电子色散x射线能谱(EDS)/扫描电镜(sem)对膜的组成进行了分析。用拉曼光谱对晶相进行区分,锐钛矿的拉曼位移约为(142.1,411.1,547.4和669.6)cm-1,金红石的拉曼位移约为(190,272,452和616)cm-1。此外,采用椭偏光谱仪(SE)研究了纳米锐钛矿(1%wt)薄膜厚度为128 nm, n = 2.25时,纳米金红石薄膜厚度为313.5 nm, n = 2.5时薄膜的厚度和折射率(n)。剖面仪研究了涂层的形貌,以证明均方根(RMS),以确定粗糙度随颗粒尺寸的增加而增加。傅里叶变换红外(FTIR)分析表明,纳米颗粒在(400-1000)cm-1之间的频率区域为Ti-O-Ti的强键,cm-1的波段分别为Si-O-Si的对称拉伸和振动。以罗丹明B (Rhodamine B, RhB)为抗氧化指示剂,对膜进行了自清洁试验。
