NOVELTY - Structural color film stabilizer comprises 1-8 pts. wt. graphene, 5-15 pts. wt. polydopamine, 55-80 pts. wt. ethanol, and 2.5-5.5 pts. wt. surfactant. USE - Structural color film stabilizer. ADVANTAGE - The structural color film stabilizer has improved stability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing structural color film stabilizer involves mixing graphene with ethanol, sonicating for 20-30 minutes, then adding surfactant and adjusting the pH of the solution to 8-9, stirring for 20-40 min, adding polydopamine and stirring for 10-20 minutes for twice, and homogenized to obtain desired product.
