Researchers have created a durable silicon polymer material that, once applied, can repel ice for years from any surface.
Icing causes significant damage to the energy, aviation and industrial infrastructure. Therefore, for a long time, researchers have been looking for a way to combat this negative factor, but scientists from the University of Houston reported significant progress in this direction. They developed a new physical theory that allows predicting and correcting the features of synthesized materials in advance..
They used their model to create a polymer that practically does not interact with ice at the molecular level, and also has excellent mechanical and chemical resistance. According to the inventors, their theory can be use to synthesize materials with various unique properties, for example, antibacterial.
The new material uses the localization of elastic energy at the junction with ice, preventing the formation of cracks that can form even with minimal exposure to external factors such as wind. The polymer is created in the form of a spray, which allows it to be applied to any surface.
Tests have shown that in addition to good mechanical resistance, it is not destroyed by ultraviolet radiation. and does not affect the aerodynamic characteristics of objects in the process of their movement. The coating can effectively perform its functions for 10 years without the need for reapplication.
The creation of another innovative material was reported by Canadian scientists. They have developed a surface coating that is capable of absorbing only one «target» substance, and all others repel.
