Tetrapod-shaped　zinc　oxide　(T-ZnO)　whiskers　were　coated　with　silver　by　chemical　plating　(T-ZnO@Ag).　T-ZnO(T-ZnO@Ag)/silicone　rubber　composites　were　fabricated　at　a　temperature　of　165　degrees　C　and　pressure　of　15MPa.　The　nonlinear　conductivity　characteristics　of　T-ZnO　(T-ZnO@Ag)/silicone　rubber　composites　with　volume　fractions　of　1vol.%,　2.4vol.%,　3.7vol.%,　and　5vol.%　were　investigated.　The　dielectric　properties　of　the　composites　at　frequencies　of　0.1Hz　to　10MHz　were　analyzed.　The　conductivity　of　the　T-ZnO/silicone　rubber　composite　increased　with　the　T-ZnO　content,　while　the　switching　field　decreased.　Upon　the　coating　of　T-ZnO　with　Ag,　the　nonlinear　characteristics　of　the　T-ZnO@Ag/silicone　rubber　composite　significantly　enhanced.　The　nonlinear　coefficient　reached　10.95　at　the　filler　content　of　2.4vol.%.　The　percolation　threshold　of　T-ZnO　fillers　is　significantly　lower　than　that　of　spherical　ZnO　fillers.　Percolation　threshold　and　Schottky　barrier　effect　were　utilized　to　explain　the　nonlinear　electrical　properties.
