International. Researchers at the University of Surrey invented a new process for making bespoke coatings that could reduce the "drag resistance" of ships and aircraft, as well as their fuel consumption.
The researchers call their process "infrared radiation assisted by evaporative lithography." They use beams of infrared light to heat certain points of wet coatings made of tiny plastic particles in the water. According to experts, the process is simple to use and does not require expensive equipment. Textured coatings can be used to cover almost any surface.
Coatings have textures that could decrease the carbon footprint in the transportation industry by reducing motion friction through air or water. In turn, ships will consume less energy in propulsion.
The project is being developed for industrial manufacturers, as an alternative to using the process to create new layers and decorate household items.
Using the simple and inexpensive process, it is possible to create plastic coatings with small bumps in sizes ranging from less than a millimeter to a couple of centimeters. With the right design, this texture will reduce trawling forces when large vessels pass through air or water.
According to Professor Joseph Keddie, who led the study, "It is a very interesting activity to have an impact on the energy consumption of aircraft and ships through simple and cheap technology. Our process can create coatings with almost any desired texture to meet the particular needs of an application."
