  • Patent number: 11401629
    Abstract: The present invention discloses a method for preparing graphene nanofibers and non-woven fabrics using a fluid with a ultra-high draw ratio by means of a high-voltage electrospinning method. Compared with other methods for preparing graphene fibers (such as wet spinning, air-assisted spinning, etc.), the graphene fibers obtained by the present method have smaller diameters (about 100 nm to 500 nm) and a higher yield. The fibers themselves have better mechanical and electrical properties. The invention discloses a method for preparing ultra-fine graphene nanofibers and non-woven fabrics by electrospinning a mixed spinning liquid system of polymer and graphene oxide (the polymer is sodium polyacrylate). This method is highly efficient and environmentally friendly, and the resulted graphene nanofibers are the thinnest graphene fibers as currently known.

  • Publication number: 20220237766
    Abstract: A measurement and reconstruction method for a turbine blade strain field of with integrates an imaging technology and an infrared photoelectric measurement technology. The imaging technology is mainly responsible for the measurement of the strain field on a target blade surface, so as to use a digital image processing technology to obtain blade strain field data. The infrared photoelectric measurement technology is mainly aimed at the strain at blade edges, which uses temperature difference between the blade edges and blade gaps to perform strain measurement. Measurement results of the two modes are finally converted into blade strain parameters, thereby reconstructing the target blade strain field based on host computer software.
