As global temperatures change, the demand for air conditioners has become more and more high, making life a necessity. However, air conditioners remain the leading cause of greenhouse gas (CO 2) emissions, which largely contribute to climate change. Therefore, the use of air conditioning can be said that a vicious cycle, but also an expensive cycle.
According to the Antarctic bears, researchers at the University of Maryland (UMCP) are working hard to develop a new type of textile designed to reduce the frequency of air conditioning use. It is reported that this textile can be regarded as a personal cooling device, without the need to use any external energy. They recently published a survey entitled "Three-Dimensional Printing Heat-Regulating Textiles" in ACSNano Magazine to explore the potential of 3D printing in the manufacture of high-tech textiles designed to keep you cool.
UMCP's research is based on the development of a variety of functional apparel, including moisture and perspiration training gear, deodorant sportswear, and garments that block UV light through chemical coatings. Although these functional textiles are rapidly emerging, the clothing that makes people feel cool is hard to achieve because of the cumbersome and expensive materials, so the UMCP team is looking for a more practical solution. They combine boron nitride, a material known for its excellent heat transfer capability, with polyvinyl alcohol. The result is a new, 3D-printable nanocomposite fiber that can be woven into different types of fabric. Tested to absorb 1.5 times more heat-absorbing capacity than virgin PVA, in other words, clothes made from this 3D printed nanocomposite keep the wearer cool and comfortable, reducing air conditioning Demand, reducing greenhouse gas emissions.
