Abstract
The application relates to the technical field of ammonia gas sensors, and discloses a preparation method of a laser-induced graphene-based ammonia gas sensor, which adopts the following technical scheme: a preparation method of a laser-induced graphene-based ammonia gas sensor, comprising the following steps: S1, laser direct writing is performed on the surface of a polyimide film through a laser engraving device to form a set of interdigital electrode patterns on the surface of the polyimide film; S2, a gas-sensitive material is prepared, the gas-sensitive material is mixed and ground with terpineol and glass beads, and then the mixed gas-sensitive material is coated on the treated polyimide film; and S3, the polyimide film obtained in the step S2 is aged at 60-70 DEG C to obtain a flexible ammonia gas sensor. The flexible substrate with interdigital electrodes can be prepared in a low-cost manner.
