  • Patent number: 11987662
    Abstract: An environmentally-friendly flexible conductive polyurethane (PU) and a preparation method thereof are disclosed. The environmentally-friendly flexible conductive PU is prepared by subjecting a mixture of a component A and a component B in a specified mass ratio to in-situ solvent-free polymerization, where the component A is prepared from a polyol, a T-type chain extender, a diselenide diol, high-conductivity carbon black, a dispersing agent, a catalyst, and a leveling agent, and the component B is prepared from a polyisocyanate, a polyol, a multi-walled carbon nanotube (MWCNT), and a dispersing agent. The PU has a reliable electrically-conductive function, and shows a self-healing function under room temperature or light conditions when damaged, wherein a microphase separation value HBI (0.5 to 3.

  • Publication number: 20240010858
    Abstract: A polyamide coating slurry and its preparing method, and a process for preparing polyamide-coated fabric for printing are provided. The present disclosure provides a polyamide coating slurry for precise inkjet printing with wide applicability simple preparation steps. The surface structure and lipophilicity of the coating can be changed by mixing polyvinyl butyral and polyoxypropylene lauryl ether, urea and poly-N-isopropylacrylamide in polyamide 6, so that the adsorption properties and permeability of the coating to ink are greatly improved, and thus high-precision inkjet printing can be realized.

  • Publication number: 20220316098
    Abstract: A graphene/polymer microsphere a modified chemical fiber filled with a multi-oriented graphene/polymer composite and a preparation method are disclosed. Graphene is coated by an in-situ suspension polymerization, which greatly improves the dispersion effect of graphene. Comonomers are used to increase the compatibility between graphene and polymers, so that a strong interaction between graphene and polymers is formed. The graphene/polymer microsphere with low melting point and high toughness is used to fill a chemical fiber, and is oriented therein to modify the chemical fiber. The graphene/polymer microspheres could be oriented to form a microfibril structure with a high aspect ratio in the chemical fiber.

  • Publication number: 20220081568
    Abstract: A method for synthesizing a polymer/pigment hybrid latex through sulfur-free and soap-free in-situ reversible addition-fragmentation chain transfer (RAFT) emulsion copolymerization includes the following: dispersing a pigment with a reactive emulsifier to prepare a pigment dispersion; synthesizing an amphiphilic sulfur-free ?-vinyl-terminated polymethyl methacrylate (PMMA) macromolecular RAFT agent in-situ on a surface of pigment particles through catalytic chain transfer polymerization (CCTP); and adding an acrylate monomer dropwise, allowing in-situ sulfur-free RAFT polymerization on a surface of pigment particles through the RAFT agent, and adjusting a structure and a composition of an encapsulated polymer layer to obtain a series of uniformly encapsulated and stably dispersed polymer/organic pigment hybrid latexes.

  • Patent number: 9375687
    Abstract: The invention discloses an environmentally-friendly pasty discharge agent for textile printing and a method for preparing the environmentally-friendly pasty discharge agent. The environmentally-friendly pasty discharge agent for textile printing is formed by the following raw materials according to part by weight: decamethylcyclopentasiloxane: 30-60 parts; thiourea dioxide: 40-70 parts; surfactant: 1-3 parts; and glycerol: 3-6 parts. Decamethylcyclopentasiloxane is put into a ball mill, a surfactant is added into the ball mill to make the decamethylcyclopentasiloxane dispersed or dissolved uniformly and then stirred uniformly, and then thiourea dioxide is added into the ball mill and ground together for 1-3 hours. In the invention, the special liquid compound decamethylcyclopentasiloxane does not chemically react with the thiourea dioxide; in addition, it isolates the thiourea dioxide from outside water and air, thus increasing the stability of the thiourea dioxide.
