通过CVD法制备碳纳米管,并用浓硝酸和浓硫酸对其酸化处理,然后使用CTAB进行修饰,最后通过结合胶实验进行橡胶补强的研究。实验表明:经过酸化处理,碳纳米管上产生较强的羟基基团,并能将CTAB吸附在碳纳米管周围;CTAB修饰后的碳纳米管的结合胶量比普通炭黑更高。 Carbon nanotubes were prepared by CVD method, acidified with concentrated nitric acid and concentrated sulfuric acid, and then modified with CTAB. Finally, the rubber reinforcement was studied by using the adhesive. Experiments show that: after acidification, strong hydroxyl groups are generated on the carbon nanotubes, and CTAB can be adsorbed around the carbon nanotubes; the CTAB modified carbon nanotubes have higher binding glue than ordinary carbon black.
