Abstract

In industrial applications, the benefits of superhydrophobic surfaces are precisely obvious, including the improvement of antiwetting, anticorrosion, anticontamination features which improve wear-resistant and provide self-cleaning properties. The difference between theoretical models and case studies shows some gap that needs to be overcome to achieve cost and energy efficiency in the development of superhydrophobic materials. Application of hydrophobicity not only prevents blockage of gas and oil walls in a long pipeline but it also reduces 25% of the adhesion between fluid and pipeline walls. A range of preparation technologies for delivering superhydrophobic properties is discussed in this chapter with their advantages, problems, and contact angle results. Coal log is a typical area in the mining industry where the future research on superhydrophobicity needs to be focused. This chapter delivers a systematic and critical review from the origin of the concept to the most recent developments in the fabrication of superhydrophobic surfaces.
