Inspired by the dyeing processes,a highly elastic and conductive transition metal carbide/nitride(MXene)-based rib knitting fabric was prepared via a scalable roll-to-roll technology,with its structure and performance characterized and evaluated by SEM,resistance measurement,sensing performance testing.The results showed that MXene-based rib knitting fabric displayed good elasticity and elastic recovery.The MXene loading in the fabric increased and the electrical resistance decreased with roll-to-roll cycles,with the lowest sheet resistance reaching 38.3 Ω/□.Data from the strain sensing performance test indicated that the MXene-based rib knitting fabric exhibited anisotropic strain sensing performance,with the strain sensing performance in course direction better than that in the wale direction.In addition,the maximum gauge factor and sensing range were 72.80 and 0～160％,respectively,higher than those in wale direction(gauge factor:4.4,sensing range:0～24％).
