Abstract:
The thermal conductances across covalently bonded interfaces between oriented single crystal diamond and completely aligned polyethylene chains are determined for the three principal orientations of diamond. The calculated thermal conductances, which range over 690-930 MW m(-2) K(-1), are consistent with those of other strongly bonded interfaces. These results suggest that the experimental interfacial conductances across hard-soft interfaces can be quite large if the bonding across the interface is strong, a conclusion that could have important implications for thermal management in bioelectromechanical systems and other inorganic-organic structures. The effects of defects and cross-linking on the thermal conductivity of polyethylene are also analyzed.

Polymer Classification: Crystallinity
Crystalline domains are the regions where polymer chains are aligned in an orderly manner and held together in proximity by intermolecular forces. For example, chains in the crystalline domains of polyethylene and nylon are bound together by van der Waals...

Molecular Weight of Step-Growth Polymers
As the step-growth polymerization involves step-wise condensation of monomers, the molecular weight also builds up eventually. Consequently, high molecular weight polymers are obtained at the late stages of the polymerization, where 99% of monomers have been consumed.
