Single-wall carbon nanotube latexes.

A nanolatex copolymer (25−30 nm) of an imidalozium bromide acrylate is reported that provides stable waterborne dispersions of single-walled carbon nanotubes (SWCNT) and thermally and electrically conducting coatings that adhere to plastics. This approach to dispersing SWCNT leaps past previous reports by providing stabilization and binder functions simultaneously. Resulting films exhibit 10-fold anisotropy in both thermal and electrical conductivity and appear free of interfacial phonon scattering problems. The electrically conducting networks assembled upon film formation provide a new route to priming plastics for electrodeposition in addition to providing simple antistatic layer formulations. The efficacy of these nanolatexes is assigned to the imidazolium and bromide components shown in other studies to have an affinity for graphene surfaces.
