Abstract
Exemplary embodiments provide materials and methods for forming CNTs-polymer composites (e.g., CNTs-SBR latex nano-composites and/or CNTs-epoxy nano-composites), CNTs-polymer concrete, and CNTs-polymer modified cementitious composites. In one embodiment, a plurality of CNTs and a surfactant-containing polymer, including a surfactant attached to a polymer chain, can be dispersed within a cementitious matrix to form a CNTs-polymer modified cementitious composite with the surfactant non-covalently bonded to one or more CNTs.
