NOVELTY - Preparation of plant nanocellulose-based flexible electromagnetic shielding film involves (S1) dissolving dispersed nano silver-graphene oxide-nanocellulose dispersion comprising 1-20 %mass 25-100 nm, preferably 25-50 nm nano-silver and 5-10 %mass graphene oxide, in a solvent comprising water, methanol, ethanol, ethylene glycol, glycerol, butanol and/or n-pentanol, (S2) ultrasonically defoaming the dispersion, vacuum-filtering to form a film, drying to obtain a nano-silver-graphene oxide-nanocellulose composite film, and (S3) reducing the nano-silver-graphene oxide-nanocellulose composite film with vitamin C. USE - Preparation of flexible electromagnetic shielding film for preparing electromagnetic shielding garment (all claimed). ADVANTAGE - The process is simple and easy. The prepared shielding film has excellent antibacterial property and electromagnetic shielding effects.
