| 英文摘要 | Resistive-type polyaniline (PANI) based sensing film was fabricated by a simple in-situ polymerization method with graphene (GP) as additives on flexible porous polyvinylidene fluoride (PVDF) substrate. The fabricated flexible GP-PANI/PVDF membrane demonstrates a multi-hierarchical porous microstructure, enhancing its sensing performance towards ammonia (NH3). The optimized GP-PANI/PVDF sensor shows 60% response towards 1 ppm NH3 with a response time of 46 s, and 10% response towards 0.1 ppm NH3 at 24 degrees C, respectively. Moreover, the GP-PANI/PVDF sensor presents excellent flexibility, exhibiting only small response values' difference upon several bending angles and after 1500 bending/extending cycles. Besides, the GP-PANI/PVDF sensor exhibits a strong linear relationship between the NH3 response values and working temperatures with a range of 24 degrees C similar to 50 degrees C. The results demonstrate that the flexible GP-PANI/PVDF film sensor holds great promise for the application of portable, lightweight, and room temperature sub-ppm level NH3 detection devices. |
