Type of article: Article

Summary

THE LATTICE THERMAL CONDUCTIVITY OF 4 SAMPLES OF POLYETHYLENE HAVING DIFFERENT DENSITIES HAS BEEN STUDIED IN THE TEMPERATURE RANGE 1-20 K IN THE FRAME OF THE EXPRESSION FOR THELATTICE THERMAL CONDUCTIVITY OF POLYMERS PROPOSED BY DUBEY ET AL. RECENTLY, AND AVERY GOOD AGREEMENT HAS BEEN OBTAINED BETWEEN CALCULATED AND EXPERIMENTAL VALUES. THE SEPARATE PERCENTAGE CONTRIBUTIONS DUE TO NON-CRYSTALLINE AS WELL AS DUE TO CRYSTALLINE STRUCTURES HAVE BEEN STUDIED AND IT IS FOUND THAT AT LOW TEMPERATURES, THE PERCENTAGE CONTRIBUTIONS DUE TO ITS NONCRYSTALLINE STRUCTURE DOMINATES OVER THE SAME DUE TO CRYSTALLINE NATURE AND VICE VERSA AT HIGH TEMPERATURES.
