▎ 摘　　要

NOVELTY - Nanomaterial bacteriostatic mask comprises filter material. The filter material comprises bamboo carbon fiber and graphene oxide. The bamboo carbon fiber is hollow in the interior and spiral tube wall. USE - Used as nanomaterial bacteriostatic mask. ADVANTAGE - The mask has small suction resistance and good filtration efficiency and solves contradiction between filtration efficiency and suction resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of nanomaterial bacteriostatic mask comprising preparing modified graphene oxide by taking 10-20 pts. wt. graphene oxide, 80-100 pts. wt. absolute ethyl alcohol, 10-20 pts. wt. fatty acid, 8-10 pts. wt. titanate, mixing, ultrasonically dispersing, heating, refluxing and reacting, filtering, washing and and drying.
