Fill the thermos cup with hot water when you go out. When you want to drink, the water in the cup is still hot. I believe many citizens have such experiences. How to keep the mug warm and maintain the ideal temperature? The graphene thermostatic water cup developed by the Chinese graphene leading company XMXC Graphene Technology Co., Ltd. solves the above problems.
"Pour boiled water into a thermos cup, and within 10 minutes, the water in the cup can quickly drop to 58 ° C. According to our tests, the temperature around 58 ° C can be maintained for about 8 hours." Liu Changjiang, Technical Director of XMXC The reporter showed this water cup. He said that the water cup can not only make the boiling water cool down quickly, but also achieve long-term temperature control.
The secret of the thermostatic cup lies in the graphene phase change material in the interlayer. The R & D team compounded the graphene material with high thermal conductivity and the phase change material to improve the thermal conductivity of the material. According to Liu Changjiang, the phase change point of the phase change material used by the R & D team is 58 ° C. After the addition of boiling water, the material undergoes a phase change and changes from solid to liquid to absorb heat, causing the water temperature to quickly drop to 58 ° C. The phase change material changes heat from the liquid state to the solid state and then releases heat, thereby achieving a constant temperature of 58 ° C.
The application of graphene phase change materials to thermos cups is another attempt of XMXC in consumer products. As an early high-tech enterprise engaged in the development and application of graphene products in China, XMXC has been committed to promoting the practical application of graphene technology. The previously developed graphene air purification treasure is quite popular in the market.
Just recently, the R & D team of XMXC aimed at the problem of easy fogging of goggles. By adding a layer of transparent conductive film of graphene on the goggles lens, the lens was heated with a dry battery to make the lens temperature consistent with the temperature of the exhaled gas , Solve the problem of lens easy to fog. At present, the prototype of this product has been released, and it is expected to be put into use in the future.
In the view of Liu Changjiang, graphene technology is gradually entering life, and the prospect of industrialization is worth looking forward to, but there is still a lack of "non-graphene materials are indispensable, and other materials are irreplaceable 'applications." He said that the development of the graphene industry requires long-term R & D investment and continuous deep cultivation. It is believed that with the cooperation of the government, enterprises and researchers, more and more achievements will emerge in the graphene industry.
