Physical adhesion of a flexible sensor with CNT@CPM and humidity dependence of different PM ratio. a Actual photograph of a humidity sensor and EDS mapping and line scanning analysis; the flexible sensor was evenly coated and revealed to be completely covered by individual CNT@CPM core–shell nanocomposites. b Sensitivity and hysteresis integrated graph, showing sensitivity was 10 to 237 Ω/%RH from 0 to 10 wt%, and hysteresis was (− 0.291 ± 0.079) ~ (0.300 ± 0.001) %. c Humidity hysteresis curves of CNT@CPM, showing high reproducibility, repeatability, and constant values; linearity reached 0.998 (R2) in CNT@CPM-3
