A superhydrophobic coating with excellent water repellence and gamma irradiation resistance was obtained by multi-walled carbon nanotubes (MWCNTs) modification. The effects of MWCNTs on the mechanical behaviour, water contact angle (WCA) and self-cleaning properties of the coatings were investigated. After 1.23×107 rad dose of gamma irradiation, WCA of the coating without MWCNTs modification (EPPM0) decreases from 150° to 140° and the adhesion reduces from 5B to 4B, respectively. While the coating (EPPM3) with 3wt% MWCNTs modification remains high WCA (152°), excellent adhesion (5B) and hardness (6H). The results of dust removal test suggest that the coating still maintains self-cleaning property after high dose gamma irradiation.
