A highly branched polymer comprising repeating units which each have an acid group such as sulfo group, said repeating units being represented by formula [1] or the like, and a dispersant for carbon nanotubes (CNTs) which comprises the highly branched polymer can disperse CNTs in a medium such as an organic solvent to the individual sizes and can yield thin films having improved conductivity.
In formula [1], any one of A1 to A5 is a sulfo group, and the others are each a hydrogen atom.
一种高支化聚合物由重复单元组成,每个重复单元都有一个酸基,如磺基,所述重复单元由式[1]或类似的式子表示;一种用于碳纳米管(CNT)的分散剂由该高支化聚合物组成,可将碳纳米管分散在有机溶剂等介质中,使其达到各自的尺寸,并可生成具有更好导电性的薄膜。
在式[1]中,A1 至 A5 中的任何一个为磺基,其他各为氢原子。
