本发明涉及一种碳纳米管及功能化碳纤维增强环氧树脂复合材料的制备方法。本发明将碳纳米管经过羧基化功能化后,在碳纳米管上引入二元胺或多元胺,得到表面胺基化的碳纳米管;将胺基化的碳纳米管与表面经过羧基化的碳纤维反应,得到胺基化的碳纤维表面接枝有碳纳米管,在碳纤维表面引入二元胺或多元胺,使碳纤维表面未完全与
The present invention relates to a method for preparing carbon nanotube and functionalized carbon fiber reinforced epoxy resin composite material. In the present invention, after the carbon nanotubes are functionalized by carboxylation, a diamine or a polyamine is introduced on the carbon nanotubes to obtain the surface-aminated carbon nanotubes; and the amino-modified carbon nanotubes are surface-modified with carboxylated Carbon fiber reaction, to obtain amination of carbon fiber surface grafted with carbon nanotubes, the introduction of diamine or polyamine in the carbon fiber surface, the carbon fiber surface is not completely and
