摘要：
This study presents a flexible layered ZnO-polycaprolactone and graphene-polycaprolactone nanocomposite sensor for UV and NO2 gas sensing applications, created by electrospinning to achieve a fibrous high surface area structure. Sensor performance was evaluated by varying ZnO concentration and sensing layer thickness, with 50 % ZnO content in the nanocomposite yielding optimal response to UV. NO2 gas sensing tests demonstrated significant resistivity changes, with Rg/Ra values reaching up to 5.65 and minimal response reduction under elevated humidity. The sensor calculated NO2 detection limit was 0.544 ppm, indicating its suitability for environmental and industrial monitoring, as well as potential integration into flexible electronics and wearable technologies.
