一种监测慢性肾脏疾病呼吸传感器的制备方法，包括气敏复合材料的制备，所述气敏复合材料是具有核壳结构的CeO2@PANI纳米线，具体是通过制备非晶态的CeO2纳米线作为内核，经氢等离子处理后，在纳米线表面包覆非晶态的PANI形成外壳。本发明中制备的核壳结构的CeO2@PANI纳米线对NH3的选择性高、灵敏度高，在常温情况下对氨气的监测性能皆高于纯的PANI和未等离子处理的样品，对于浓度为100ppm时的氨气的响应达到了670%，对NH3的最低检测限值可低至50ppb；响应时间快、回复时间短，且随着放置时间的延长，响应时间缩短至45s，回复时间缩短至417s。 A preparation method of a respiration sensor for monitoring chronic kidney diseases comprises preparation of a gas-sensitive composite material which is a CeO2 (at) PANI nanowire with a core-shell structure, and specifically comprises the following steps: preparing an amorphous CeO2 nanowire as an inner core, carrying out hydrogen plasma treatment, and coating the surface of the nanowire with amorphous PANI to form a shell. The CeO2 (at) PANI nanowire with the core-shell structure prepared in the invention has high selectivity and high sensitivity on NH3, the monitoring performance on ammonia gas at normal temperature is higher than that of pure PANI and a sample which is not subjected to plasma treatment, the response on ammonia gas
