Description

technical field [0001] The present application relates to the technical field of gas sensors, in particular to a gas sensor for detecting organic phosphorus compounds and a preparation method thereof. Background technique [0002] Gas sensor is an important branch of sensing technology, which can convert the information related to gas type and concentration into electrical signal, so as to detect, monitor, analyze and alarm. According to the gas-sensitive material used in the gas sensor and the effect of the interaction with the gas to be measured, the gas sensor is mainly divided into semiconductor gas sensor, solid electrolyte gas sensor, contact combustion gas sensor, optical gas sensor, quartz Resonant gas sensors and surface acoustic wave gas sensors, etc. Traditional gas detection instruments are bulky and expensive, so it is imperative to develop miniaturized and integrated gas sensors with high performance. [0003] With the rapid development of organic semiconduct...
