许多努力都集中在提高湿度传感器的湿度传感性能，但他们的制造使用方便和低成本的方法也是可取的。在这项工作中，一种基于天然纳米材料海泡石纳米纤维（snf）的湿度传感器，无需任何昂贵的原材料或复杂的工艺即可轻松制成。表征结果表明，snf具有天然细长的纳米纤维结构（直径20 ~ 50 nm）和丰富的亲水性官能团（-OH）。湿感测试结果表明，在室温（25℃）相对湿度10.9% ~ 91.5%范围内，SNF湿度传感器具有显著的湿感性能（响应大、线性度好、重复性好）。本研究提出了一种使用天然SNF纳米材料制造高性能湿度传感器的适度且具有成本效益的策略。
Much effort has focussed on enhancing the humidity-sensing performances of humidity sensors, but their fabrication using facile and low-cost methods is also desirable. In this work, a humidity sensor based on a naturally available nanomaterial, sepiolite nanofibers (SNFs), was facilely fabricated without any expensive raw materials or complex processes. Characterization results show that SNFs have a natural slender nanofiber structure (diameter 20-50 nm) and abundant hydrophilic functional groups (-OH). The results of humidity-sensing tests show that the SNF humidity sensor has outstanding humidity-sensing properties (i.e. large response, good linearity and repeatability) within the relative humidity range from 10.9% to 91.5% at room temperature (25 degrees C). This work presents a moderate and cost-effective strategy for the fabrication of high-performance humidity sensors using the natural SNF nanomaterial.
