However, one of typical drawbacks in carbon-based sensors is incomplete recovery to their initial state after chemical reactions with analytes, degrading sensing reproducibility. In this work, we present a thermally stable and robust boron nitride nanotube/carbon nanotube (BNCNT) hybrid paper for self-enhanced chemiresistive sensing with full reversibility. Boron nitride nanotube (BNNT) plays an essential role in long-term reliability (33 days) at the operating temperature of 200 °C. In addition, a finite-element method was applied to understand the thermal behavior of the BNCNT network structure. The BNCNT paper-based chemiresisitve sensor exhibited highly sensitive, selective, and fully reversible responses to NO2 without external heating. Also, the sensor demonstrated the detection limit of parts per billion (ppb)-levels under strain with high reliability. With these remarkable strengths, significantly facile and cost-effective fabrication processes provide an environmental sensing platform for use in smart clothing with wearable electronics. ？ 2021 English Elsevier BV Boron nitride/carbon nanotube composite paper for self-activated chemiresistive detection Article 10.1016/j.snb.2021.131273 1 Sensors and Actuators, B: Chemical, v.355 Sensors and Actuators, B: Chemical 355 N scie scopus 000744963200006 2-s2.0-85121460331 Chemistry, Analytical Electrochemistry Instruments & Instrumentation Chemistry Electrochemistry Instruments & Instrumentation Article GAS-SENSING PROPERTIES CARBON NANOTUBES ELECTRONIC NOSE GRAPHENE OXIDE TEMPERATURE HUMIDITY SENSOR NANOSTRUCTURES Boron-nitride/carbon nanotube hybrid Chemiresistive sensor Fully-recovered CNT sensor NO2 sensor
