Polymer-derived ceramic (PDC)-based high-temperature thin-film sensors (HTTFSs) exhibit promising applications in the condition monitoring of critical components in aerospace. However, fabricating PDC-based HTTFS integrated with high-efficiency, high-temperature anti-oxidation, and customized patterns remains challenging. In this work, we introduce a rapid and flexible selecting laser pyrolysis combined with a direct ink writing process to print double-layer high-temperature antioxidant PDC composite thin-film thermistors under ambient conditions. The sensitive layer (SL) was directly written on an insulating substrate with excellent conductivity by laser-induced graphitization. Then, the antioxidant layer (AOL) was written on the surface of the SL to realize the integrated manufacturing of double-functional layers. Through characterization analysis, it was shown that B₂O₃ and SiO₂ glass phases generated by the PDC composite AOL could effectively prevent oxygen intrusion. Therefore, the fabricated PDC composite thermistors exhibited a negative temperature coefficient in the temperature range from 100 to 1100 °C and high repeatability below 800 °C. Meanwhile, it has excellent high-temperature stability at 800 °C with a resistance change of only 2.4% in 2 h. Furthermore, the high-temperature electrical behavior of the thermistor was analyzed. The temperature dependence of the conductivity for this thermistor has shown an agreement with the Mott’s variable range hopping mechanism. Additionally, the thermistor was fabricated on the surface of an aero-engine blade to verify its feasibility below 800 °C, showing the great potential of this work for state sensing on the surface of high-temperature components, especially for customized requirements.

激光热解快速打印高温聚合物陶瓷复合薄膜热敏电阻

基于聚合物衍生陶瓷 (PDC) 的高温薄膜传感器 (HTTFS) 在航空航天关键部件的状态监测中展现出有前景的应用。然而，制造集成高效、高温抗氧化和定制图案的基于 PDC 的 HTTFS 仍然具有挑战性。在这项工作中，我们介绍了一种快速灵活的选择激光热解结合直接墨水书写工艺在环境条件下打印双层高温抗氧化PDC复合薄膜热敏电阻。通过激光诱导石墨化将敏感层（SL）直接写入具有优异导电性的绝缘基板上。然后，在SL表面写入抗氧化层（AOL），实现双功能层的集成制造。通过表征分析表明，PDC复合AOL生成的B ₂ O ₃和SiO ₂玻璃相能够有效阻止氧侵入。因此，所制备的PDC复合热敏电阻在100至1100℃的温度范围内表现出负温度系数，并在800℃以下表现出高重复性。同时，它在800℃下具有优异的高温稳定性，2小时电阻变化仅为2.4%。此外，还分析了热敏电阻的高温电气行为。该热敏电阻的电导率的温度依赖性与莫特的可变范围跳跃机制一致。此外，该热敏电阻被制作在航空发动机叶片的表面上，以验证其在800℃以下的可行性，显示了这项工作在高温部件表面状态传感方面的巨大潜力，特别是对于定制需求。
