whose thermal conductivity could be improved by doping or stretching methods etc
but a single polyethylene chain owns a considerably high thermal conductivity. For polyethylene chains
a detailed calculation is made on the thermal conductivity of original single chain
several chains
torsional chains and stretching chains using equilibrium molecular dynamics methods. Results show that
the thermal conductivity of a single torsional chain decreases slightly
but the thermal conductivity of several chains improves a little when the chains twisted in a particular way. Besides
the thermal conductivity of several chains could achieve a great improvement under stretching loading. Based on above results
a torsional and stretching strand accompanied by better heat-conducting properties is introduced. It has a great significance in guiding the improvement work of the heat conduction of polymer chains under a variety of physical loading.
