Abstract

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
