Abstract
本发明公开了基于新型的有机半导体材料的气体传感器及其制备方法，包括通过缩聚的方式制备n型半导体聚苯并咪唑苯并菲咯啉；将n型半导体聚苯并咪唑苯并菲咯啉与聚乙烯亚氨按照预定比例混合，并将混合物加入到分散剂中超声分散2‑3h得到分散液；制备叉指电极，并将叉指电极附着在基底上得到MEMS芯片；将分散液滴涂至MEMS芯片表面并进行干燥形成气敏单元。本发明气体传感器的敏感材料采用n型半导体聚苯并咪唑苯并菲咯啉和聚乙烯亚氨的复合材料，该传感器可对对二氧化氮进行痕量检测，其室温下灵敏度可比肩高温状态下金属氧化物材料，同时其响应、恢复时间大大缩短，避免了金属氧化物传感器在使用过程中需加热的情况，降低了体系的能量消耗。
