Abstract: The present invention deals with a methodology of incorporating carbon nanotubes (CNTs) into an epoxy matrix and thereby producing epoxy-based CNT nanocomposites. Both the pristine and ozonized CNTs are almost homogeneously dispersed into the resin by this approach. Compared with the pristine CNTs (p-MWCNTs), the ozonized ones (f-MWCNTs) offer considerable improvements on mechanical properties within the epoxy resin.
