Surface Engineering Plasmas for Enhanced Technologies and Greener Societies


Date: TBA


With an expanding world population on a finite Earth, resources have been rapidly diminishing. Bulk materials are now in high demand everywhere and the demand in functionalities cannot be met by those materials anymore. Introducing surface functions on bulk materials can enable much needed resource savings and more efficient use of energy sources.

In this review, we will present a survey of this field with an emphasis on passive systems using an interaction with their environment for energy gains in particular. Many environmental stimuli

can be tapped by smart surfaces made from physically interacting materials. Typically, parameters such as temperature, humidity, or illumination are such interesting stimuli.

Here, we will review existing and promising solutions brought thanks to plasma processing. Non-equilibrium plasmas enable low-temperature, tailored energy delivering to surfaces and we will review in particular combined effects that can be exploited, for renewable energies or property enhancements in natural resources, such as smart blades for water turbines.
