Preparation and Characterizaion of Hydrophobic Transparent Hard Sol–Gel Nano-Composite Films Lanfang Yao a, Shuo Wangb, Lin Li, Ruiqing Xu, Yuping Chen, Junlong Kang College of Science, University of Shanghai for Science and Technology, Shanghai, 200090, China ayao_lanfang@126.com, bwangshuo7106686@sina.com Keywords: Sol–Gel; Hydrophobic; Transparent; Hard; Nano-Composite Film Abstract.
Therefore, in recent decade years, the preparations of the hydrophobic films have become an important study direction in material science field [1~3].
Scratch resistant hard coating materials have been formulated by the sol–gel process and applied to materials surfaces.
Organic functionalization of silicates permits precise control over the surface properties, modification of hydrophobic of the surface; alteration of the surface reactivity, protection of the surface from attack, modification of the bulk properties of the materials and at the same time stabilizing the materials towards hydrolysis.

Hybrid membrane is a combination of polymer materials that composed at least two different polymers of organic and inorganic materials.
Methodology 2.1 Materials 2.1.1 Materials for characterization of wastewater In the preparation to determine the characteristics of wastewater, two sources of wastewater solution from Company A were used.
Distilled water and deionized water was obtained from the environmental laboratory, Faculty of Civil Engineering, UiTM Shah Alam. 2.1.2 Preparation of thin film composite membrane The materials required for the preparation of composite membrane were obtained from Sigma Aldrich, Malaysia.
All of these materials were employed without further purification. 2.2 Methods 2.2.1 Characterization of Industrial Wastewater The wastewater was characterized by using the tests below: 2.2.1.1 Biochemical Oxygen Demand (BOD) The BOD test was conducted according to standard method ASTM D888 [11].
