Abstract
Exemplary embodiments provide nanotube-containing coating compositions and methods for making and using the coating compositions. In an exemplary embodiment, the coating composition can include a plurality of nanotubes (e.g., carbon nanotubes (CNTs)) dispersed stably and uniformly in a polymer matrix containing fluoropolymers. The coating composition can further include stabilizers to allow a stable and/or uniform dispersion of the plurality of nanotubes in the fluoropolymers. The nanotube coating composition can be coated on an article surface to improve mechanical robustness, and electrical and thermal conductivity of the coated article. The coated article can be used as a fuser member, a fixing member, a pressure roller, or a release agent donor member in an electrostatographic printing machine or process.
