▎ 摘  要

NOVELTY - Preparing super-hydrophobic electromagnetic shielding fabric, comprises (i) pretreating fabric, placing pretreated fabric in the first treatment solution for the first soaking treatment, taking out to maintain a 100% margin rate and placing in a self-sealing bag, allowing to stand for 6-12 hours, removing first treatment solution on the surface of the fabric and drying t to obtain cationized fabric, adding graphene nanosheets into deionized water, and stirring to obtain a second treatment solution, placing cationized fabric in second treatment solution, and subjecting to a second soaking treatment, taking out, repeatedly washing with deionized water and drying, adding the perfluorosulfonic acid solution to equal amounts of deionized water and anhydrous ethanol, mixing uniformly, adding multi-walled carbon nanotube nano-powder, placing graphene nano-sheet fabric in a third treatment solution for a third soaking treatment, performing drying treatment and repeating cycle many times. USE - The method is useful for preparing super-hydrophobic electromagnetic shielding fabric. ADVANTAGE - The preparation method of super-hydrophobic electromagnetic shielding fabric has excellent hydrophobic and good electromagnetic shielding performance, and after soaking for a long time, still has obvious electromagnetic shielding property, and excellent ventilation and comfortable hand feeling, so that it has excellent service performance. The method is simple and has strong operability. DETAILED DESCRIPTION - Preparing super-hydrophobic electromagnetic shielding fabric, comprises (i) pretreating fabric, placing pretreated fabric in the first treatment solution for the first soaking treatment, taking out to maintain a 100% margin rate and placing in a self-sealing bag, allowing to stand for 6-12 hours, removing first treatment solution on the surface of the fabric and drying t to obtain cationized fabric, adding graphene nanosheets into deionized water, and stirring to obtain a second treatment solution, placing cationized fabric in the second treatment solution, and subjecting to a second soaking treatment, taking out, repeatedly washing with deionized water and drying to obtain a graphene nanosheet fabric, adding the perfluorosulfonic acid solution to equal amounts of deionized water and anhydrous ethanol, mixing uniformly, adding multi-walled carbon nanotube nano-powder, ultrasonically treating, and dispersing uniformly to obtain a third treatment solution, placing graphene nano-sheet fabric in a third treatment solution for a third soaking treatment, performing drying treatment and repeating cycle many times to obtain a superhydrophobic electromagnetic shielding fabric.
