摘要：
PROBLEM TO BE SOLVED: To provide a method for producing a carbon nanotube dispersion, by which a carbon nanotube dispersion excellent in dispersibility and stability can easily be produced at a low cost. SOLUTION: A surfactant having an alkyl ester group, a vinylidene group and an anionic substituent (e.g. a dodecyl itaconate) is used as a dispersant. Carbon nanotubes are added to the aqueous solution of the dispersant and ultrasonic treatment or bead mill treatment is conducted, whereby a carbon nanotube dispersion excellent in dispersibility and stability can be produced. The carbon nanotube dispersion thus obtained is applicable to various purposes such as a wet friction material, a CNT film, a polymeric composite material using CNT as a filler, an environmental conservation and restoration material, a CNT cell culture substrate and an electromagnetic wave shielding material.

摘要（中）：
解决问题：提供一种碳纳米管分散体的制造方法，能够以低成本容易地制造分散性和稳定性优异的碳纳米管分散体。 溶液：使用具有烷基酯基，亚乙烯基和阴离子取代基（例如衣康酸十二烷基酯）的表面活性剂作为分散剂。 将碳纳米管加入到分散剂的水溶液中，进行超声波处理或珠磨机处理，由此可以制造分散性和稳定性优异的碳纳米管分散体。 由此获得的碳纳米管分散体可适用于湿摩擦材料，CNT膜，使用CNT作为填料的聚合物复合材料，环境保护和还原材料，CNT细胞培养基板和电磁波屏蔽材料等各种目的 。 版权所有（C）2010，JPO＆INPIT
