Superhydrophobic Organic-Inorganic Nanohybrids

WithChang-Sik Ha, Saravanan Nagappan

This chapter describes the updates of the fabrication of superhydrophobic organic-inorganic nanohybrid surfaces using chemical and physical approaches. Click chemistry is widely used for the synthesis of UV-curable polymers and materials as well as for the synthesis of organic-inorganic hybrid coating materials. The emulsion synthesis of hydrophobic coating agents has attracted considerable interest in the fabrication of superhydrophobic organic-inorganic nanohybrid substrates because of the controlled particle size and shape, stability, easy usage, and ability to adhere to various substrates. The surface grafting and polymerization of the methyl methacrylate monomer was carried out on a copper substrate in the presence of the electro-initiated redox activation of aryl diazonium salts. Chemical routes are simple methods for fabricating superhydrophobic organic-inorganic nanohybrid surfaces. Self-assembly involves the combination of smaller or larger units of molecules by spontaneous interactions in solution or gas phase. Solution immersion is the most prominent method to fabricate a superhydrophobic coating due to easy and simple method of surface modification.
