Abstract

Hydrophobicity is the physical property of a surface that avoid water.Basically,carbon and hydrogen atoms are the only molecules in the hydrophobic surface.This surface cannot interact favourably with water and repel water that make a contact with the surface.This property of the surface can be measured or classified by referring to the contact angle of the droplet on the surface.Contact angle is the most important criteria to analyse the wettability of the surface.Small contact angle is smaller than 90º it show high wettability,whereas large contact angle which exceed 90º correspond to low wettability.Contact angle can be describe as the angle formed by meeting of liquid with solid surface.The shape of the liquid drop to be measured as contact angle is determined by surface tension of the liquid.The purpose of this project is to develop an innovative contact angle measurement tools for the hydrophobicity analysis with low cost of manufacturing proces but get the high accuracy of the result.Since the previous product on market has high cost to buy it and also used advanced technology and advanced software which make users complex to handle the equipment.Furthermore the product is quiet big and stationary and only can be used in the laboratory only which is cannot be move from a place to another place. After complete the product,a few series of testing was conduct to test the accuracy of the result and compared with the previous study with high technology method.Then the result will validate using Minitab software to conduct the test for One Sample T Test and Normality Test for both samples.
