Abstract
Wetting plays a crucial role in achieving efficient condensation in applications such as atmospheric water harvesting, air conditioning and refrigeration, and thermal power plants. Despite decades of research, the industrial implementation of dropwise condensation, which is often superior to filmwise condensation, has been limited, mostly due to the poor durability of promoter coatings and the challenge of achieving dropwise condensation for non-aqueous working fluids. Both areas have seen noteworthy advancements over the past few years, some of which we highlight in this review article. For example, recognizing that contact angle hysteresis, not contact angles per se, are responsible for enabling dropwise condensation, ultra-smooth liquid-like polymer coatings and lubricant-infused surfaces were developed for use with water and non-aqueous working fluids. There are also several new developments for passive and active droplet removal. Advances in coating durability include a better understanding in the failure mechanisms and physics-informed designs of new coating processes and chemistries.
期刊介绍:
Current Opinion in Colloid and Interface Science (COCIS) is an international journal that focuses on the molecular and nanoscopic aspects of colloidal systems and interfaces in various scientific and technological fields. These include materials science, biologically-relevant systems, energy and environmental technologies, and industrial applications.
Unlike primary journals, COCIS primarily serves as a guide for researchers, helping them navigate through the vast landscape of recently published literature. It critically analyzes the state of the art, identifies bottlenecks and unsolved issues, and proposes future developments.
Moreover, COCIS emphasizes certain areas and papers that are considered particularly interesting and significant by the Editors and Section Editors. Its goal is to provide valuable insights and updates to the research community in these specialized areas.
