Thermally induced atomization during droplet impingement on superheated hydrophobic and superhydrophobic surfaces

Preparation of the Temperature-Responsive Superhydrophobic Paper with High Stability

“…Studies have found some common environmentally responsive superhydrophobic surfaces, such as light response, temperature response, pH response, electric field response, ionic liquid response, and magnetic response. − Nowadays, a lot of waste oil and water mixtures are produced in the industrial production process, and superhydrophobic materials can not only separate these mixtures through filtration or single-phase selective absorption, but also realize the free switching of oil–water separation according to production needs in different external environments, which shows their strong industrial application value. Therefore, the preparation of intelligent responsive materials has become an important issue of industrial production. − However, due to the high cost and complex preparation process, their application value in industrial production is limited to a certain extent. , After experimental research and practical verification, it is gradually found that temperature-responsive superhydrophobic surfaces have the advantages of a fast response, low requirement of preparation equipment, and simple preparation process, which make them show a greater production and application value and also set off an upsurge of academic research on temperature-responsive superhydrophobic surfaces. , …”

Hydrodynamic pattern transition of droplet train impinging onto heated titanium substrates with or without nanotube coating

“…Droplet impinging onto heated and coated surface has gained extensive attention since it is related to many important industrial applications, such as film coating, spray coating, spray cooling and combustion [1]. Many efforts have been conducted to explore the heat transfer and hydrodynamics of single droplet impingement [2], two droplet impingement simultaneously [3,4] and droplet train impingement [5].Effects of the impinged surfaces conditions, such as different wettability [6,7], stationary dry surface [8],stationary pre-wetted surface [9], surface with liquid film [10,11] and moving surface [12], etc, have been investigated and discussed.…”
