▎ 摘 要
NOVELTY - Preparing biomass colloid gel comprises dispersing anthraquinones small molecule and porous graphene in sodium bicarbonate solution or phosphate buffer solution to obtain mixture, the mass ratio of the anthraquinone small molecule to the porous graphene is 1:0.14-7, the pH value of the mixture is 8-10, ultrasonically cooling the mixture under the condition of 30-70℃ to obtain the biomass colloid gel. USE - Method for preparing biomass colloid gel, which is used as the printing ink formulation material. ADVANTAGE - The method has good temperature responsiveness, the test shows that the biomass colloid gel excellent specific capacity, obvious shear, large characteristics strain, self-healing characteristics non-frequency dependence and time stability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for use of the biomass colloid gel as the printing ink formulation material.
