News from our newspaper (Reporter Wang Daqian) Wuhan has made another great achievement in overcoming the world's problems in the detection of nano-scale thin-film materials-the "Hubei Engineering Laboratory of Functional Thin-Film Material Physical Performance Testing Technology" was established in Wuhan Future Science and Technology City. The laboratory It was jointly prepared by Wuhan Jiayitong Technology Co., Ltd. and Huazhong University of Science and Technology.

With the development and application of new materials, nano-scale thin film materials are widely used in many fields, but there is no equipment that can directly detect the thermal properties of thin films in the world. "1 nanometer is only one-sixty thousandth of the diameter of a hair strand. How to detect the thermal characteristics of the film has become an international problem." said Wang Yuanbing, general manager of Jiayitong Company. Destructive testing can only be carried out after the film material is scraped off to form a certain quality of powder.

After years of technical tackling, the team of Professor Miao Xiangshui, a "Yangtze River Scholar" from Huazhong University of Science and Technology, led the team to develop my country's first optical power thermal analyzer, which can detect the thickness of the film up to 5 nanometers. According to reports, the optical power thermal analyzer irradiates the laser onto the surface of the nano-film material, and detects the phase transition temperature point and thermal expansion coefficient of the film through the reflected light power. This scientific and technological achievement was successfully transformed in Jiayitong and moved towards industrialization.

As the first domestic functional film material physical performance testing technology research base, after the establishment of a provincial engineering laboratory, it will be equipped with film material thermal analysis, film material sample preparation and processing, film material electromagnetic analysis, film material mechanical analysis, and film material. Five vertical research laboratories for optical analysis of materials.

"Thin film materials are a disruptive technology to global scientific and technological progress. As thin film technologies become thinner and thinner, disruptive test equipment is needed." Professor Pan Feng of Tsinghua University and head of the expert group of the National Key R&D Program told the Changjiang Daily reporter, Science and Technology The Ministry has set up a major research and development project for material genomes. One of the important tasks is to overcome high-throughput characterization and detection technology. Hubei can rely on the leading advantages of thin film detection research and development to make greater scientific contributions.
