Hydrogen sensor and preparation method therefor, and method for implementing hydrogen detection

摘要

A hydrogen sensor and preparation method therefor, and a method for implementing hydrogen detection using the hydrogen sensor. The hydrogen sensor comprises an elastic substrate and a hydrogen sensitive material-based nanofilm positioned on the elastomeric substrate. The preparation method for the hydrogen sensor comprises the following steps: mixing a liquid elastomeric material and a curing agent, and uniformly stirring the mixture to obtain a mixed liquid, wherein the mass ratio of the liquid elastomeric material to the curing agent is 5:1-20:1; removing bubbles in the mixed liquid; drying and curing the mixed liquid in which bubbles are removed to obtain an elastomeric substrate; and depositing a hydrogen sensitive nanomaterial on the elastomeric substrate to form a hydrogen sensitive material-based nanofilm. The hydrogen sensor and the method for implementing hydrogen detection using the hydrogen sensor feature high sensitivity and simple production.
