摘要:
This study was carried out to discuss the influence of curing temperature on the performance of conductive composites filled with nickel-coated graphite (NCG). The electrical conductivity, crosslink density, mechanical properties and tensile fracture morphology have been investigated. The results indicated that curing temperature had great impact on the electrical conductivity and mechanical properties. Voluem resistivity decreased from 43.1 to 0.08 ohm-cm at 125 degrees C-205 degrees C, and the reason was discussed in light of formation and break of the conductive network in the composites. The stability of SR-NCG cured at 165 degrees C-205 degrees C were also better than those cured at other curing temperature. Besides, tensile strength increased from 2.41 to 7.19Mpa at 125 degrees C-225 degrees C, elongation at break have a 56% increase, and Shore A hardness also incresed from 74 to 82.
