摘要： Disclosed are a paper-based electromagnetic shielding composite with flame retardant properties and its preparation method and application, belonging to the technical field of electromagnetic shielding. In the present disclosure, PI fibers are modified by polydopamine and grafted with carbon nanotubes, polyimide fiber paper is prepared by a wet papermaking technology, an in-situ synthesis method is used to enable conductive MOFs and polymer PPy to grow on the fiber paper, and finally polyimide resin is sprayed onto the paper to prepare the paper-based electromagnetic shielding composite with flame retardant properties. The method is simple in process without complex synthesis equipment, and solves the problems that polyimide fiber paper is poor in paper forming property and paper mechanical property, and carbon nanotubes are easy to agglomerate in paper and limited in addition amount in the prior art. The paper-based composite has good mechanical property, heat resistance, flame retardancy and electromagnetic shielding performance.

摘要： The present disclosure relates to electromagnetic shielding paper based on modification of a conductive MOF material and a preparation method thereof, and belongs to the technical field of electromagnetic shielding. The method includes the following steps: putting polyimide fibers into a precursor solution of the conductive MOF material, and reacting to obtain MOF material modified PI fibers; mixing the modified fibers with aramid pulp, and carrying out papermaking, squeezing and drying to obtain a paper-based precursor; generating a conductive polymer (polypyrrole) in situ by using a gas-phase polymerization method, and finally obtaining the electromagnetic shielding paper based on the modification of the conductive MOF material. The electromagnetic shielding paper prepared by the present disclosure not only has good conductivity and electromagnetic shielding performance, but also has good mechanical properties and thermal stability.

摘要： The present disclosure discloses a pad-steam bleaching method based on a TBLC-activated hydrogen peroxide system, and belongs to the field of pretreatment processing of textiles. According to the pad-steam bleaching method based on the TBLC-activated hydrogen peroxide system, TBCC and H2O2 are compounded with a weak base to prepare a TBCC/H2O2/weak base system for performing near-neutral bleaching on cotton fabrics; the fabrics are padded and then steamed to be bleached. By the method disclosed by the present disclosure, the whiteness of fabric treated for 2 minutes by a TBCC/H2O2/sodium citrate padding and steaming system is significantly superior to that of fabric treated for 60 minutes by an H2O2/NaOH dip bleaching system. The CIE whiteness of the fabric reaches 77 and above, the fabric wettability after treatment is also improved, the damage of the fabric is smaller, and the amount of water used by the method is small. The fabric only needs to have a certain wet pick-up, and a large amount of fabric can be treated by a certain volume of solution, which effectively reduces waste water treatment, saves energy and protects the environment; the method requires a short treatment time and has high bleaching efficiency.
