文摘

The surfactant-free inks yield resistivity ρ values are 7× lower, i.e. 1.1 mΩ m, compared to 7.1 mΩ m for the surfactant-assisted formulations. Mechanical elasticity and robustness of the printed structures reveals minimal variations in resistance (∼8%) with bending radii of curvature up to 0.16 cm−1. Thermal behavior of the printed features formed using the surfactant-free ink yields low temperature coefficient of resistivity, i.e. 1 Ω/K in the range of 6–80 K, or −2.7 × 10−4 ppm/K.
