NOVELTY - A nano titanium graphene oxide composite tanning agent comprises 40-50 pts. wt. titanium salt solution, 40-50 pts. wt. graphene oxide nano sheet suspending liquid, and 5-8 pts. wt. dispersant solution. USE - A nano titanium graphene oxide composite tanning agent for leather. ADVANTAGE - The agent has leather absorption rate of 95%, reduces leather shrinkage by 5%, and improves flexibility and elasticity of leather. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method of preparing a nano titanium graphene oxide composite tanning agent comprising mixing graphene oxide nano sheet suspending liquid and dispersant solution, subjecting to ultrasonic wave treatment for 30-40 minutes, adding monomer mixed solution, stirring, and regulating pH value to 4-5.
