A review of physics of moving contact line dynamics models and its applications in interfacial science

Despite several decades long research on moving contact line dynamics due to its remarkable role in interfacial science and technological fields, there is still a significant lack of comprehensive knowledge about the true nature of the contact line. The moving contact line is much more complex than just a geometric flow condition. Given the role of moving contact line physics in numerous emerging advanced technologies including bioprinting, tissue engineering, pharmaceutical industry, smart functional coatings, flexible electronics, and healthcare, it is needed for scientific community to direct their focus in advancement on better understanding of interfacial science and physics of moving contact line. Therefore, this review primarily concentrates on the current physical theories which describe the moving contact line dynamics. Moreover, numerous potential and ongoing applications of moving contact line dynamics linked to the interfacial science are thoroughly discussed. Finally, this review presents the future perspectives related to the current challenges in moving contact line dynamics.
