Abstract

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 R_g/R_a 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.

期刊介绍： The journal provides an international medium for the publication of theoretical and experimental studies and reviews related to the electronic, electrochemical, ionic, magnetic, optical, and biosensing properties of solid state materials in bulk, thin film and particulate forms. Papers dealing with synthesis, processing, characterization, structure, physical properties and computational aspects of nano-crystalline, crystalline, amorphous and glassy forms of ceramics, semiconductors, layered insertion compounds, low-dimensional compounds and systems, fast-ion conductors, polymers and dielectrics are viewed as suitable for publication. Articles focused on nano-structured aspects of these advanced solid-state materials will also be considered suitable.
