In this study, conductive composites of methyl vinyl silicone rubber (MVQ) filled with nickel‐coated graphite (NCG) were prepared. The effects of the storage time, aging time, stretching, neutral‐salt spraying, and acid‐salt spraying on the electrical conductivity of NCG/MVQ were investigated. The results indicate that the values of the NCG/MVQ volume resistivity increased a little and were no greater than 0.1 Ω cm after long‐term storage, thermooxidative aging, stretching, and neutral‐salt spraying, respectively; this showed good conductive stability. The volume resistivity rose rapidly under acid‐salt spraying; this indicated poor conductive stability. © 2012 Wiley Periodicals, Inc. J Appl Polym Sci, 2012
