Abstract
A copolymer of polytetrafluoroethylene and a perfluoro acid (e.g., Nafion™) is neutralized by a base to yield its corresponding salt, and a high-boiling-point compatible solvent is used as a substituting solvent, with the original, low-boiling-point solvent being removed by rotor evaporation. The resulting dispersion is screen printable, and its viscosity is controllable by adjusting its solids content. This screen-printable salt dispersion is especially useful in printed electronics applications such as sensors.
