Understanding Heat Conduction in Oriented Polymers

  • Martin Pietralla
Part of the NATO ASI Series book series (NSSB, volume 258)


It is shown why heat conduction generally becomes anisotropic in oriented polymers. In semicrystalline polymers the smallness of the crystals introduces additional size effects, e. g. the existence of non-propagating acoustical modes. In the superstructure phonon focussing appears. The influence of these effects on the conduction mechanism is discussed.
