摘要: Graphene oxide (GO) was functionalized with a series of amine precursors including ammonia, methylamine, ethylamine, ethylenediamine, dimethylamine, aniline, and 1, 4-phenylenediamine (PDA) by a facile solvothermal method for room temperature formaldehyde (HCHO) gas sensing. The as-prepared materials were fabricated via a simple drop-casting method and screened based on the response to 300 ppm HCHO gas at room temperature. GO functionalized with 1, 4-phenylenediamine (PDA-GO) was the most …
