Embodiment 1
[0024] Follow the steps below to prepare graphene composite antibacterial fiber:
[0025] (1) After the graphene oxide is treated with a plasma with a power of 100W for 5 minutes, it is added to an ethanol aqueous solution with a volume fraction of 80%, stirred until the mixture is uniform, and then N-β-(aminoethyl)-γ-aminopropyl is added Methyldimethoxysilane and water were stirred and reacted for 3.5 hours to obtain reaction solution 1. The filter residue obtained after filtering the reaction solution was dried at 80°C to obtain aminated graphene, graphene oxide, ethanol aqueous solution, and N-β -(Aminoethyl)-γ-aminopropylmethyldimethoxysilane and the mass ratio of water are 1:30:0.4:18;
[0026] (2) Add the aminated graphene obtained in step (1) to water, stir until the mixture is uniform, add glycidyltrimethylammonium chloride, heat to 80°C and stir for 1.5 hours to obtain reaction solution two, and add the reaction solution two The filter residue obtained after filtration is...
Embodiment 2
[0030] Follow the steps below to prepare graphene composite antibacterial fiber:
[0031] (1) After the graphene oxide is treated with a plasma with a power of 100W for 5 minutes, it is added to an ethanol aqueous solution with a volume fraction of 80%, stirred until the mixture is uniform, and then N-β-(aminoethyl)-γ-aminopropyl is added Methyldimethoxysilane, water, stir and react for 3 hours to obtain reaction solution 1. The filter residue obtained after filtering the reaction solution is dried at 80°C to obtain aminated graphene, graphene oxide, ethanol aqueous solution, N-β -(Aminoethyl)-γ-aminopropylmethyldimethoxysilane and the mass ratio of water are 1:30:0.4:18;
[0032] (2) Add the aminated graphene obtained in step (1) to water, stir until the mixture is uniform, add glycidyltrimethylammonium chloride, heat to 80°C and stir for 2 hours to obtain reaction solution two, The filter residue obtained after filtration is dried at 80°C to obtain quaternized graphene, and the ...
