摘要: 本工作以简单水热法合成了纳米片组装的花状LiFePO4微球，在材料表征的基础上，首次探究了其湿敏性能。LiFePO4微球的特殊形貌和较大的比表面积有利于暴露更多活性位点，提升湿敏性能。测试结果表明，基于LiFePO4的湿敏传感器件具有良好的湿敏性能，显示了三个数量级的响应值(1.5 × 103)，并具有较短的响应时间(15 s)，展示了人体皮肤湿度监测的应用潜力。本工作不仅提供了一种优异的湿敏材料，而且扩展了LiFePO4的应用范围。
Abstract: In this work, flower-like LiFePO4 microspheres were synthesized by a simple hydrothermal method. After material characterization, the humidity sensing performance of the LiFePO4 sample was explored for the first time. LiFePO4 microspheres featuring special morphology and a large specific surface area can provide more active sites for boosted humidity sensing. The test results show that the humidity sensor based on LiFePO4 shows good humidity sensitivity, as high as three orders of magnitude (1.5 × 103), and short response time (15 s), demonstrating the application potential of human skin moisture monitoring. This work not only provides an excellent humidity sensing material, but also expands the application scope of LiFePO4.
