| Title: | Surface acoustic wave sensor for formaldehyde gas detection using the multi-source spray-deposited graphene/PMMA composite film | Authors: | Wang, B Zhou, L Wang, X |
Issue Date: | 2022 | Source: | Frontiers in materials, 2022, v. 9, 1025903 | Abstract: | A surface acoustic wave (SAW) formaldehyde sensor based on a graphene/polymethyl methacrylate (PMMA) composite film with high sensitivity, and short response and recovery time was proposed in this study. Using a novel multi-source spray deposition method, graphene sheets were uniformly dispersed in a PMMA film to fabricate sensitive films with a three-dimensional framework structure for use in SAW devices. The formaldehyde-sensing ability was enhanced by optimizing the film thickness and operating temperature. The highest performance was achieved for a graphene/PPMA film thickness of 2.2 μm at a temperature of 120°C. | Keywords: | Formaldehyde Graphene Polymer Polymethyl methacrylate Sensor Surface acoustic wave sensors |
