Abstract: An anti-tamper module includes a substrate and a photoisomerization (PI) layer formed on the substrate. The PI layer comprises molecules configured to transition from a first state to a second state in response to exposure to a first type of light and transition from the second state to the first state in response to exposure to a second type of light, and transitioning a selected portion of the PI layer to the first state while surrounding portions of the PI layer remain in the second state causes physical deformation of the PI layer. An excitonic layer is arranged on the PI layer. An electrical characteristic of the excitonic layer is sensitive to strain caused by the physical deformation of the PI layer such that an excitonic property of the excitonic layer changes in a region corresponding to the selected portion of the PI layer.

Abstract: Methods of increasing thermal conductivity of a bulk polymer are provided. The methods include contacting a bulk polyelectrolyte polymer comprising an ionizable repeating pendant group with an aqueous liquid having a pH that ionizes the pendant group and isotropically extend the polyelectrolyte polymer to an extended non-globular chain conformation. The polyelectrolyte polymer so treated thus exhibits a thermal conductivity of greater than or equal to about 0.6 W/m·K and optionally greater than or equal to about 1 W/m·K. In other aspects, the present disclosure provides a high thermal conductivity material comprising a bulk polyelectrolyte polymer bearing a repeating charged group and having an extended non-globular chain conformation and that exhibits a thermal conductivity of greater than or equal to about 0.6 W/m·K and optionally greater than or equal to about 1 W/m·K. The high thermal conductivity material may be used in electronic devices, including as housings/encapsulation and thermal interfaces.
