摘要：
Understanding the behavior of a surface is important for various applications. Non-wettable surfaces inspired from lotus leaf phenomenon was described by Wenzel and Cassie Baxter theories. Hydrophobic surface can be obtained by enhancing surface roughness which is inversely proportional to the surface energy. The determination of Hamaker's constant is necessary for the calculation of surface energy. Here in this work surface roughness and energy of various silane and polymer blend were calculated using Hamaker's constant which implies hydrophobicity. (C) 2019 Elsevier B.V. All rights reserved.
