Abstract
that are made up of oriented polymer chains are provided. Chains of polymer may be oriented or substantially aligned in one or more directions exhibiting enhanced thermal conductivity along the direction of orientation. Orientation of polymers within sheets may lead to a wide range of thermally relevant applications.
Claims37
A sheet material comprising:
- at least one layer having a width and length substantially larger than a thickness and includes a layer of substantially aligned polymer chains, wherein the layer of substantially aligned polymer chains exhibits anisotropic thermal conductivity.

A method of forming a polymer sheet, comprising:
- providing a polymer precursor having a first polymer chain orientation;
- and
- modifying the first polymer chain orientation of the precursor to form a sheet having a second polymer chain orientation in which chains are substantially more aligned than the first polymer chain orientation and such that the sheet exhibits anisotropic thermal conductivity.
