Kerala University secures patent for breakthrough in solar reflective pigment technology

Kerala University has been awarded an Indian patent for an innovative process to produce solar reflective spinel pigments, marking a significant step forward in the development of dark infrared (IR) reflective coatings.

The technology, spearheaded by Professor S.M.A. Shibli and his research team at the Department of Chemistry and the Centre for Renewable Energy and Materials, has the potential to enhance energy efficiency across a wide range of applications. The research team included Sameera S., Aysha Shafna M. and Muhammed Hilal E.K.

The patent, facilitated by the Technology Incubation Programme for Startups – Technology in Medicine and Devices (TIPS-TIMeD), was filed through the university’s Patent Cell at the Translational Research and Innovation Centre.

According to an official release, these novel pigments possess unique properties, allowing them to reflect a significant portion of solar radiation while maintaining a dark appearance. This characteristic makes them ideal for use in coatings on buildings, vehicles and other surfaces where heat absorption needs to be minimised without compromising aesthetics.

The patented method is not only cost-effective but also environmentally friendly, offering a promising route for large-scale industrial application.
