Patents by Inventor Hujun Qian

Hujun Qian has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Acrylate-based single-chain nanoparticles and aqueous phase photochemical macroscopic preparation method thereof
    Patent number: 12187820
    Abstract: An acrylate-based single-chain nanoparticle is disclosed, which includes 10-20 parts of methacrylic acid, 1-2 parts of tetramethylguanidine and 1-2 parts of halohydrocarbon. The scheme provided by the disclosure establishes a “meta template” for synthesizing various single-chain nanoparticles, unifies the preparation method of the polyacrylate, simultaneously carries out high-concentration preparation in an aqueous phase only through ultraviolet irradiation, which reduces the production cost, reduces the carbon emission in production, and provides possibility for the industrialized production of the polyacrylate-based single-chain nanoparticle.
    Type: Grant
