纤维素醚基传感器的研究进展

随着柔性可穿戴设备的快速发展，传统的半导体、陶瓷等材料难以广泛地单独应用于柔性传感器领域。天然纤维素来源广泛，是一种良好的柔性材料，但存在不能熔融、难溶于常规溶剂、理化性能差等问题，而纤维素醚能有效改善天然纤维素的上述问题，因此在传感、储能、产能和柔性器件等领域作为绿色基材得到了初步开发。基于纤维素醚基材料在便携化、多功能化、生物相容性等方面的良好性能，及其应用于柔性传感领域的巨大潜力，本文综述了纤维素醚的制备及纤维素醚基材料在应力应变传感、温/湿度检测、气体传感、离子检测等领域的最新研究进展，分析了纤维素醚基传感器应用前景和未来发展面临的挑战。

Research Progress of Cellulose Ether-based Sensor

With the rapid development of flexible wearable devices， traditional materials such as semiconductors and ceramics cannot be widely used in the field of flexible sensors alone. Natural cellulose， which is derived from various sources， is a good flexible material. However， there are several issues associated with natural cellulose， including its inability to be melted， difficulty in dissolving in conventional solvents， and poor physical and chemical properties. To address these problems， cellulose ether has been developed to enhance natural cellulose. It serves as a green substrate and had shown promising potential in the areas of sensing， energy storage， energy production capacity， and flexible devices. This paper focused on the preparation of cellulose ethers and the latest research progress in cellulose ether-based materials for stress-strain sensing， temperature/humidity detection， gas sensing， and ion detection. Additionally， it analysed the application prospects of cellulose ether-based sensors and identified the challenges for future development.
