Plasma-controlled surface wettability: recent advances and future applications

Abstract

Materials with the desirable surface wettability are of key importance in diverse applications. However, most of the existing chemical processes used for surface wettability control are often energy-inefficient, pollute the environment, and rely on harsh processing conditions. Therefore, highly-selective, green, and low-cost alternative fabrication techniques are in urgent demand. Low-temperature plasma processing is one such promising approach that satisfies the above requirements. In this review, we present recent advances in plasma processing to control surface wettability for diverse emerging applications in the environment, energy, and biomedicine fields. The underlying mechanisms of the plasma surface engineering, key features of the fabrication processes, and water-surface interactions are discussed. This review aims to guide further development of the plasma processing to effectively control the surface wettability of various surfaces. This effort is poised to contribute to the development of advanced functional materials targeting a broad range of applications.

Bubble Management for Electrolytic Water Splitting by Surface Engineering: A Review

“…Until now, more fabrication processing and functional strategies appeared such as hydrothermal codeposition, the ionic layer adsorption method, the vapor-assisted treatment approach, and electrochemical deposition . For instance, Dastafkan et al simply synthesized a vanadate-modified iron–nickel catalyst.…”

Plasma electrode dielectric barrier discharge: development, characterization and preliminary assessment for large surface decontamination

“…Typically, in an APPJ electric discharge is ignited in a noble gas that ows through a dielectric channel and the resulting plasma is ejected into the surrounding environment (usually ambient air), forming a plasma plume [1]. As the plasma stream propagates into the surrounding atmosphere [2], it interacts with the ambient molecules creating reactive oxygen and nitrogen species (RONS) that upon reaching a target can induce surface modi cation [3,4] and decontamination [5] effects. The plasma jets are characterized by diverse geometries and electrode con gurations and can be driven by pulsed DC, AC, RF and microwave sources using different operating parameters, which makes them very versatile [1,4].…”

Control strategies for atmospheric pressure plasma polymerization of fluorinated silane thin films with antiadhesive properties

“…[5][6][7][8] Therefore, these films are suitable for numerous industrial applications, including optics, electronics, and medical devices. [9][10][11][12][13] Despite plasma polymerization being traditionally performed at low pressure (10-100 Pa), atmospheric pressure plasma polymerization is receiving increasing attention due to the absence of expensive vacuum equipment and the possibility of in-line processing. [14][15][16][17] However, at atmospheric pressure, the mean free path of reactive species is significatively shorter than at low pressure, thus resulting in more complex gas chemistry.…”
