摘要：
Temperature-resistivity behaviour of carbon nanotubes (CNTs)/ultrahigh molecular weight polyethylene (UHMWPE) conductive composite with a 2-dimensional conductive network is investigated. The composite, in which CNTs were only dispersed in the interface of matrix particles, experiences a positive temperature coefficient of resistivity (PTCR) around the melting point followed by a negative temperature coefficient of resistivity (NTCR), and the resistivity begins to rise abruptly at the maximum crystallization temperature during cooling. The composite has a low PTC and NTC effec, which is determined by its 2-dimensional conductive network and the properties of the matrix.
