Researchers at Donghua University have developed a new type of fabric that can cool the wearer. This material is made of several different polymers in a relatively simple way, which can effectively transfer heat and absorb sweat, while still being waterproof on the outside. The material is mainly composed of three parts: polyurethane constituting the basic structure, waterproof fluorinated polyurethane and thermally conductive boron nitride nanosheets. The three are combined and run through an electrospinning instrument to form a nano-fiber membrane. This may not be the smartest cooling material, but the team says it is relatively easy to produce. In addition to clothes used to help the wearer cool down, the team said that this new material can also be used to cool electronic products and improve equipment that collects solar energy or desalinates seawater. The research was published in the journal ACS Applied Materials & Interfaces.
