Abstract
Graphene(GR) have developed rapidly since 2004, when the graphene monolayer was successfully stripped by British physicists Novoselor and Geim. Porous graphene and graphene oixde have attracted more and more attention and researches because of the porous graphene ,its special three-dimensional defect structure, high specific surface area, and high electronic conductivity. Compared with the inert graphene surface, the structure of porous graphene material can promote material transport efficiency, and hole structure can also open the energy band. These characteristics enable it to be applied to electronic devices such as super capacitor, chemical sensor, FET and other aspects. With the continuous discovery of preparation methods and characteristics of porous graphene and graphene oxide, the application of porous graphene in optical fiber sensor auniquerea has obtained great achievements. In this paper, the principle and device performance of the optical fiber sensor made by porous graphene and graphene oxide were comprehensively described and summarized.
