The University of Nottingham develops new composite materials that cool themselves at extreme temperatures

The University of Nottingham is developing a cutting-edge material inspired by nature that regulates its own temperature and can also be used to treat burns and help the capsules withstand atmospheric pressure.

The research paper, Temperature-Dependent Polymer Absorbers, is a switchable state NIR reactor and is published in the journal Science Report. “One of the main challenges of materials science is how to adjust the temperature of human body materials, just like the relationship between human body and the environment,” explains Dr. Mark Alston, assistant professor of environmental design at the School of Engineering.

This study uses multiple microchannel networks with active flowing fluids (fluids) as a method and proof of concept for developing thermally functional materials made from synthetic polymers. The material is enhanced by precise control measures that switch the conductive state to manage its own temperature associated with its environment. “This bio-inspired engineering approach facilitates the structural assembly of polymers for advanced materials. Nature uses fluids to regulate and manage mammals and plant temperatures, and absorbs solar radiation through photosynthesis. This study uses a leaf model to simulate Works in the polymer."

Dr. Alston added: "This method will produce an advanced material that can absorb high solar radiation, as the human body can do, it can be automatically cooled no matter what environment it is placed in. The thermal functional material can be used Used as a calorie conditioning system for burns, lowering skin surface temperature, monitoring and improving healing."

This heat flow management can also prove to be invaluable in space flight, where high solar loads can cause thermal stress to the structural integrity of the capsule. By adjusting the temperature of the structural material of the vehicle, this not only improves structural performance but also produces useful power. This thermal energy can be removed from the recirculating fluid system for storage in a storage tank on the capsule. Once captured, energy can be converted to electrical energy or heated water for use by the crew. The experimental aspects of the study were laboratory-based and developed in collaboration with the UK Government Research Institute: Scientific Research Facility Committee (SRFC). The next step in the study is to ensure funding for demonstrators to fund aerospace manufacturing and identify industrial partners.
