Patents by Inventor Fangong KONG

Fangong KONG 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: 11946246
    Abstract: The present invention provides an energy-storing temperature control material, and belongs to the technical field of temperature control materials. In the energy-storing temperature control material provided in the present invention, the organic synthetic fiber based phase-change material has a three-dimensional dispersion effect, and can form a network constraint for remaining phase-change materials to reinforce mechanical properties of the materials, thereby fixing shapes of the materials and avoiding a liquid-crystal phase separation phenomenon in the phase-change process. The phase-change energy storage agent can absorb and release the heat by means of solid-liquid phase conversion of the material, to achieve the temperature control effect; and the phase-change temperature regulator can regulate a phase-change temperature range of the phase-change material, to make the energy-storing temperature control material suitable for climatic features of northern China.

  • Patent number: 11220446
    Abstract: An acidic water-based process was developed for the synthesis of anionic lignin copolymers with adjustable MW, thermal stability and solubility in water. The anionic lignin copolymer described herein comprises: a molecular weight of 5,000 to 7.4×105 g/mol; and a charge density of ?1 to ?7.2 meq/g. The anionic lignin copolymers described herein which have a molecular weight range of 000-50,000 g/mol can be used as dispersants of negatively charged molecules or particles in numerous process or wastewater streams (e.g. concrete admixtures, gypsum slurries, textile dye) while such copolymers in a molecular weight range of 90,000-740,000 g/mole can be used as flocculants of positively charged molecules or particles in numerous process and wastewater streams including industrial and municipal systems and sludge dewatering in the textile dye, pulp & paper, mining and oil industries.
