Abstract

　カーボンナノチューブ（以下ＣＮＴと略す）の材料としての応用を広げるには、溶媒中にＣＮＴを単分散させることが必要である。しかし、ＣＶＤ法等により製造される長いＣＮＴは分子間引力により互いに凝集し束を作ってしまい、溶媒中に単分散させることが困難であるため、長いＣＮＴを切断して短くする必要がある。そこで、本発明は、量産性に優れ、ＣＮＴの長さを制御して切断できるＣＮＴの切断方法を提供する。 　本発明に係るＣＮＴの切断方法は、ＣＮＴとマスク用分子とを溶媒中で混ぜ合わせて前記ＣＮＴの所々を前記マスク用分子で覆う被覆工程と、前記マスク用分子で覆われた前記ＣＮＴを過酸化水素溶液中で光照射しつつ加熱することによって、前記マスク用分子で被覆されていない部分のＣＮＴを酸化消滅させる酸化工程とを有することを特徴とする。
