- Abstract
The poor structure stability of graphene limits its application as radical scavenger under γ-rays environment because of short service life. Hence we applied polyaniline (PANI), a fairly stable material under irradiation, to modify graphene and then obtained the PANI functionalized graphene oxide (PGO). According to TEM and BET data, the structure stability of PGO is much better than GO after 500 kGy irradiation doses. Electron spin spectroscopy data reveal that PGNS0.10 (PGO/PANI coatings, 0.10 wt%) are not almost affected by adverse influence comes from active radicals. Then PGNS0.10 exhibits the excellent corrosion protection performance after 500 kGy irradiation doses.
