Abstract:
     The invention discloses an electrical heating compound material for measuring temperature, which comprises 6~9% weight percentage multi-walled carbon nanotubes, 91~94% weight percentage high density polyethylene. The method for making the compound material comprises: weighing multi-walled carbon nanotubes powder and high density polyethylene in proportion; mixing them and placing them into a model; pre-heating 5~20 minutes in 165~180 centigrade, pressing 5~20 minutes under 5~30 MPa pressure; stripping membrane and cooling to room temperature. The inventive compound material takes high density polyethylene as base, multi-walled carbon nanotubes as additive, which make the compound material has great conductivity and electrical heating performance and be used to temperature measurement in a certain temperature range.
