Abstract:
1. A CNT-enhanced FRP composite, comprising: a) a fibrous material; b) functionalized CNTs coated on the fibrous material, wherein the functionalized CNTs comprise derivatives of acid-treated and sidewall fluorinated CNTs, wherein the derivatized CNTs are functionalized with carboxyl groups on their ends and at least one of amino-terminated functional groups and hydroxyl-terminated functional groups on their sidewalls; and c) an epoxy polymer matrix; wherein the derivatized CNTs are covalently integrated with the epoxy polymer matrix through covalent bonds comprising: covalent ester bonds between the carboxyl groups on the ends of the derivatized CNTs and the epoxy polymer matrix, and covalent bonds between the functional groups on the sidewalls of the derivatized CNTs and the epoxy polymer matrix.
