Novel ice-repelling coating developed

Researchers have created a durable silicone polymer coating capable of repelling ice from any surface.

Icy weather is blamed for multi-billion dollar losses every year in the US, including delays and damage related to air travel, infrastructure and power generation and transmission facilities, said researchers from the University of Houston.

Finding effective, durable and environmentally stable de-icing materials has been stymied by the stubborn tenacity with which ice adheres to the materials on which it forms, they said.

In the journal 'Materials Horizons', the researchers reported a new theory in physics called stress localisation, which they used to tune and predict the properties of new materials.

Based on those predictions, they have created a durable silicone polymer coating capable of repelling ice from any surface.

"We have developed a new physical concept and the corresponding icephobic material that shows extremely low ice adhesion while having long-term mechanical, ...
