Current trend in fabrication of complex morphologically tunable superhydrophobic nano scale surfaces

Abstract

Superhydrophobic surfaces are found in nature and possess several fascinating properties, including the ability to self-clean. A typical superhydrophobic surface has micro/nanostructure roughness and low surface energy, which combine to give it its unusual anti-wetting properties. Because of their unique capabilities, these surfaces have interested scientists in research and industry fields for years. In recent decades, researchers have developed a number of synthetic methods for producing novel superhydrophobic surfaces that mimic natural surfaces. These synthetic surfaces have been widely applied on different types of substrates for potential widespread, practical applications. This review article focuses on these advances in fabricating manmade superhydrophobic surfaces.

Novel Medium-density Fibreboard Produced by Ultrasonic-assisted Pulp with Superhydrophobic and Flame-Resistant Properties

“…2d, the average particle size of the FAS modified silica particles was approximately 100 nm to 200 nm. Liu et al (2015) and Ali et al (2016) obtained similar conclusions that the coating surface exhibited a rough, wrinkled, hill-like morphology similar to the microstructure of the lotus leaf (rough micro-scale papillae), which is promising for superhydrophobicity.…”

Biomimetic taro leaf-like films decorated on wood surfaces using soft lithography for superparamagnetic and superhydrophobic performance

“…2a clearly shows the morphology of taro leaf surface, and the honeycomb units and ellipsoids were covered with rectangular plates nanostructure that were vertically set on edge. The superhydrophobicity of the taro leaf had been widely attributed to the arrangement of protuberances microstructure and plates nanostructure [24]. Figure 2b shows the SEM image of the PDMS stamps, and microgrooves were observed on the stamp surface random, but proportionally spaced, which completely reversed with the honeycomb units on the taro leaves surface.…”

“…Известно, что в ряде работ системы с высоки-ми значениями угла смачивания получены из рас-творов с использованием гидрофобизированного кремнезема [10,11]. Это обусловлено подходящим для достижения состояния Касси размером частиц этого материала и относительной лёгкостью введе-ния его в полимерные матрицы.…”
