以聚乙烯吡咯烷酮(PVP)纳米纤维为模板，采用原位电纺和焙烧法制备了掺杂镁、钠离子的金红石型二氧化钛纳米纤维。将所制备的复合纳米纤维旋涂在带有三对碳叉指电极的陶瓷衬底上，以测量其湿敏行为。该产品具有检测水分的高速响应(2s)和恢复(1s)。此外，在紫外线照射下，产品的水接触角(θ)接近0°，使我们的湿度传感器具有防雾性能。
Mg2+and Na+doped rutile TiO2nanofibers have been prepared through in situ electrospinning technique and calcination with poly(vinyl pyrrolidone) (PVP) nanofibers as sacrificed template. The as-prepared composite nanofibers are spin-coated onto a ceramic substrate with three pairs of carbon interdigital electrodes to measure its humidity sensing behaviors. The product exhibits high-speed response (2s) and recovery (1s) for detecting moisture. Additionally, under UV irradiation, a water contact angle (θ) of nearly 0° has been observed based on the product, providing our humidity sensor with the anti-fogged properties.
