    • PURPOSE: A manufacturing method of high-dispersed carbon nanotube for reducing in vivo immune toxicity is provided to enhance dispersibility by performing and repeating ultrasonication. CONSTITUTION: A manufacturing method of high-dispersed carbon nanotube for reducing in vivo immune toxicity comprises next steps: a first step of mixing carbon nanotube in a strong acid solvent in order to introduce a functional group containing oxygen to surface of the carbon nanotube; a second step of carbon nanotube ultrasonication in the solvent; and repeating the first and the second step successively. The strong acid solvent is sulfuric acid, nitric acid, or a mixture thereof. The first step comprises the next step: stirring carbon nanotube in a mixture which has 3:1 ratio of sulfuric acid to nitric acid with a speed of 250-320 RPM for 15-45 minutes.
    • 目的:提供用于降低体内免疫毒性的高分散碳纳米管的制造方法,以通过执行和重复超声波处理来提高分散性。 构成:用于降低体内免疫毒性的高分散碳纳米管的制造方法包括以下步骤:将碳纳米管在强酸溶剂中混合以将含氧官能团引入到碳纳米管的表面的第一步骤; 在溶剂中碳纳米管超声波处理的第二步; 并连续重复第一和第二步骤。 强酸溶剂是硫酸,硝酸或它们的混合物。 第一步包括下一步骤:以250-320RPM的速度将硫酸与硝酸的比例为3:1的混合物中的碳纳米管搅拌15-45分钟。
