▎ 摘  要

NOVELTY - Graphene ion anti-virus and antibacterial liquid comprises 30-40 pts. wt. antibacterial modified graphene, 5.8-7 pts. wt. nano titanium dioxide, 2.5-2.9 pts. wt. stabilizer, and 200-400 pts. wt. deionized water. The antibacterial modified graphene is prepared by adding graphene oxide to flask containing deionized water, ultrasonically dispersing for 30 minutes, then using aqueous ammonia with concentration of 2 mol/l to adjust the pH to 10, adding antibacterial modifier, stirring for 5-10 minutes, blowing in nitrogen, ultrasonically dispersing at room temperature for 30 minutes, heating up to 80degrees Celsius, reacting for 3-4 hours, then filtering, washing for 3 times using absolute ethanol and deionized water, and drying in vacuum at 50-60degrees Celsius for 24 hours to prepare antibacterial modified graphene. USE - Used as graphene ion anti-virus and antibacterial liquid. ADVANTAGE - The antibacterial modifier has two chloramine structures with antibacterial effects and hydrophilic side chain with positive and negative charges, has amino groups that can be combined with graphene oxide well, reduces the number of oxygen-containing groups in graphene oxide, which not only makes it have better antibacterial effects, can also increase its solubility, so that the prepared anti-virus and antibacterial liquid has long-lasting excellent anti-virus and anti-bacterial effects. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the graphene ion anti-virus and antibacterial liquid, comprising (1) adding antibacterial modified graphene and quarter of deionized water into the reactor, stirring and mixing at 90-95degrees Celsius, while stirring, adding nano-titanium dioxide, after the froth appears, reducing the temperature to 70-80degrees Celsius, and removing the froth at the same time to obtain a mixed liquid, and (2) adding stabilizer to the mixed solution, stirring for 10-20 minutes, then allowing to stand for 7-9 hours, then ultrasonically dispersing for 20 minutes, then adjusting the pH to 7.8-8.2, adding the remaining deionized water, and mixing to prepare the graphene ion anti-virus and antibacterial liquid.
