  • Method for preparation of plasma-treated nanofiber-based hydrogen gas sensing material
    Patent number: 12258703
    Abstract: The present disclosure provides a preparation method of a plasma-treated nanofiber-based hydrogen gas sensing material, including the following steps: (1) stirring a mixed solution of absolute ethanol, polyvinyl pyrrolidone (PVP), N,N-dimethylformamide, SnCl2·H2O, and Zn(CH3COO)2·2H2O uniformly on a constant-temperature magnetic stirrer to obtain a spinning solution; (2) electrospinning the spinning solution and depositing on an aluminum foil to obtain a spinning fiber; (3) annealing the spinning fiber in a muffle furnace to obtain a hydrogen gas sensing material sample; and (4) subjecting the hydrogen gas sensing material sample to a vacuum argon plasma treatment with a Hall ion source to obtain the nanofiber-based hydrogen gas sensing material. In the method, nanofibers are prepared by electrospinning and subjected to the vacuum argon plasma treatment through the Hall ion source.
