Summary:The invention discloses an OTFT ammonia gas sensor embedded with a small molecule additive and a preparation method of the OTFT ammonia gas sensor. When the small molecule additive is arranged in an organic semi-conductor layer, a solution continuous processing method or a solid-state diffusion method is adopted, and therefore the OTFT ammonia gas sensor embedded with the small molecule additive at least containing one cyano group or fluoro group is obtained, wherein the solution continuous processing method is used for spin-coating or dip-coating the surface of the prepared organic semi-conductor film with an orthogonal solution containing the small molecule additive, and the solid-state diffusion method is used for coating the surface of the prepared organic semi-conductor film with thesmall molecule additive material through vacuum thermal evaporation. According to the OTFT ammonia gas sensor, the problem that an existing OTFT ammonia gas sensor is poor in stability is solved whilethe high sensitivity of t
