【Abstract】 Used epoxy resin compounding with a little organic silicone, the organic silicone’s transference characteristic has been investigated by means of multifunction electronic energy chart experiment. The temperature chart of dielectric performance and dynamic mechanics performance have also been studied in the experiments .The results show that the organic silicone has trend of surface enrichment in the composition system; dielectric constant decreases with the organic silicone consistency increasing; dielectric loss factor changes little in low temperature but increases quickly in the high; energy storage modulus decreases with silicone consistency increasing, but loss modulus increases instead.更多还原
