Abstract

Surface acoustic wave (SAW) sensors based on reduced graphene oxide/poly (diketopyrrolopyrrolethiophene-thieno [3,2-]thiophene-thiophene) (rGO/DPP2T-TT) composite sensing films for the detection of ammonia were investigated at room temperature in this study. The rGO/DPP2T-TT composite films were deposited onto ST-X quartz SAW resonators by a drop-casting method. FESEM, EDS, and XRD characterizations showed that the rGO/DPP2T-TT composite film was successfully synthesized and exhibited numerous wrinkles and a rough structure, which are crucial for gas adsorption. The frequency response to 500-1400 ppb ammonia shown by the prepared SAW sensor coated with rGO/DPP2T-TT composite film increased linearly as the ammonia concentration increased. The sensor based on a rGO/DPP2T-TT composite film exhibited a positive frequency shift of 55 Hz/ppm, and its frequency response to 500 ppb ammonia was 35 Hz. The sensors thus show promising potential in detecting sub-ppm concentration levels of NH at room temperature, which opens up possibilities for applications in the noninvasive detection of NH in the breath. As a result, the rGO/DPP2T-TT composite sensor can be a good candidate for in situ medical diagnosis and indoor/outdoor environment monitoring.

摘要

本研究在室温下采用基于还原氧化石墨烯/聚（二酮吡咯并吡咯二噻吩-噻吩）（rGO/DPP2T-TT）复合传感膜的声表面波（SAW）传感器来检测氨。通过滴铸法将 rGO/DPP2T-TT 复合膜沉积到 ST-X 石英 SAW 谐振器上。FESEM、EDS 和 XRD 表征表明，成功合成了 rGO/DPP2T-TT 复合膜，并呈现出许多褶皱和粗糙结构，这对于气体吸附至关重要。用 rGO/DPP2T-TT 复合膜涂覆的制备的 SAW 传感器对 500-1400 ppb 氨的频率响应随氨浓度的增加呈线性增加。基于 rGO/DPP2T-TT 复合膜的传感器显示出 55 Hz/ppm 的正频率偏移，其对 500 ppb 氨的频率响应为 35 Hz。因此，这些传感器在室温下对亚 ppm 浓度水平的 NH 具有良好的检测潜力，这为非侵入性检测呼吸中的 NH 开辟了可能性。因此，rGO/DPP2T-TT 复合传感器可以成为原位医疗诊断和室内/室外环境监测的良好候选者。
