1. a kind of highly dielectric elastomer composite of low content CNT, it is characterised in that using thermoplastic polyurethane asMatrix, uses array carbon pipe for dielectric filler, prepares polyurethane/carbon nano-tube dielectric elastomer material;

  • (1) by 100 mass partsPolyurethane is put into banbury, 170 DEG C of heating meltings;

    (2) 5 mass parts CNTs are gradually put into banbury, mixing is equalIt is even;

    (3) hot pressing is carried out by 170 DEG C ×

    10min on 25 tons of electrothermal plate vulcanizers that production is manufactured in Shanghai rubber manufacturing machinery, then is pressedRoom temperature ×

    10min is cold-pressed, and obtains polyurethane/carbon nano-tube composite material, and above-mentioned polyurethane is thermoplastic polyurethane;

    Gao JieConductive elastic composite material dielectric constant 9053KHz, modulus of elasticity 6.23MPa, dielectric constant/modulus is 1453.13.
