The effect of proton irradiation on the properties of a graphene oxide paper.

ABSTRACT: A graphene oxide paper (GOP) was irradiated with 500 keV proton for total fluence of 2 × 10¹³ cm^-2 to 2 × 10¹⁵ cm^-2 in a ground-based irradiation simulator. The spacing of layer, surface chemical composition, structural defects, thermal conductivity and electrical property of the GOP before and after irradiation was measured. The results indicated that the spacing of layer decreased after irradiation. The ratio of total carbon atom and total oxygen atom increased from 2.40 to 4.31 as well as the sp² hybridized carbons obviously increased after 2 × 10¹⁵ cm^-2 irradiation. The XPS analysis suggested the occurrence of reduction, and the Raman spectra indicated that the defects were produced after proton irradiation. F
