Patents by Inventor Wang-Tsai Gu

Wang-Tsai Gu 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).

  • Patent number: 8415408
    Abstract: The invention provides a germs resisting and self-cleaning infiltration thin film and manufacturing method thereof. At first, a Polyethyleneimine (PEI) and a Polyvinyl Alcohol (PVA) are used to make a polymer thin film. Then, a germ resistant and an inorganic metal oxide are added into the polymer thin film to form the selective infiltration thin film capable of resisting germs and self-cleaning.
    Type: Grant

    Assignee: Chung-Shan Institute of Science and Technology, Armaments Bureau of National Defense
    Inventors: Cheng-Chien Yang, Kuo-Hui Wu, Wang-Tsai Gu, Yu-Zen Hsieh, Mang-Zhi Wu
  • Patent number: 8119722
    Abstract: The invention discloses a polyaniline/c-MWNT produced by carboxylating at least one carbon nanotube to form at least one carboxylic carbon nanotube; mixing the at least one carboxylic carbon nanotube with a solvent to form a first carbon nanotube solution; mixing at least one aniline monomer with the first carbon nanotube solution to form a second carbon nanotube solution; mixing an ammonium persulfate solution with the second carbon nanotube solution to form a third carbon nanotube solution; air-extracting and filtering the third carbon nanotube solution to obtain the polyaniline/c-MWNT nanocomposite; cleaning and baking the polyaniline/c-MWNT nanocomposite.

  • Patent number: 8052997
    Abstract: The invention discloses an anti-bacterial composition and method for producing the same. The anti-bacterial composition of the invention includes an organic siloxane material which comprises an amino group, and a plurality of silver atoms. Particularly, the organic siloxane material has a meshed structure, and the plurality of silver atoms are bonded to the amino group and are well dispersed in the meshed structure.

  • Patent number: 8048340
    Abstract: The invention discloses a polyaniline/c-MWNT nanocomposite and a method for fabricating the same. The method comprises the following steps: carboxylating at least one carbon nanotube to form at least one carboxylic carbon nanotube; mixing the at least one carboxylic carbon nanotube with a solvent to form a first carbon nanotube solution; mixing at least one aniline monomer with the first carbon nanotube solution to form a second carbon nanotube solution; mixing an ammonium persulfate solution with the second carbon nanotube solution to form a third carbon nanotube solution; air-extracting and filtering the third carbon nanotube solution to obtain the polyaniline/c-MWNT nanocomposite; cleaning and baking the polyaniline/c-MWNT nanocomposite. The polyaniline/c-MWNT nanocomposite fabricated by the method could be used for electromagnetic shielding or anti-static shielding.
