Description

technical field [0001] The invention relates to the field of water-based coating adhesives, in particular to a water-based coating adhesive for antistatic and electromagnetic shielding fabrics based on carbon nanotubes and graphene composites and a preparation method thereof. Background technique [0002] Static electricity is caused by contact, and there will be contact and separation between clothing and human body, clothing and clothing. Therefore, static electricity is everywhere and everywhere in daily life. Static electricity provides some convenience to people's production and life, but also brings a lot of trouble and even harm. In dry climates in winter, static electricity causes clothing, especially synthetic textile clothing, to stick to the body, making it uncomfortable to wear. Static electricity makes textiles easy to absorb dust and difficult to purify, which destroys the clean environment, thus affecting the production of precision materials, especially elec...
