Highly sensitive room temperature organic vapor sensor based on polybenzoxazine-derived carbon aerogel thin film composite

- Activated carbon aerogel with high surface area can be prepared from polybenzoxazine.
- Activated carbon aerogel enhances the adsorption capacity of gas sensor.
- Organic vapors with very low concentration can be detected by the as-prepared sensor.
- The as-prepared sensor shows impressive short exposure and recovery time.
- The response to different organic vapors can be tailored by changing polymer matrix.
