What we do

We are working towards the development of electrically conductive and superconductive polymers (plastics) with their incorporation into electronic devices and equipment.

Our projects

Electrically conductive polymers

Resistivity, conductivity and sheet resistance of several samples. Note that there are nearly 10 orders of magnitude in difference between the highest resistance sample and the lowest.
Sample Resistivity Conductivity Sheet Resistance

Sample 1 1x106 9.8x10-7 3.9x1010
Sample 2 4700 2x10-4 1.2x109
Sample 3 64 0.016 5x106
Sample 4 2.7 0.37 6.7x105
Sample 5 0.17 5.9 4.3x104
Sample 6 6.6x10-4 1500 1.6x102

The number of applications for electrically conductive polymers is increasing; this is due to the inherent flexibility, robustness and comparative low cost of plastics. However, conductive polymers have a relatively high electrical resistivity and are inappropriate for certain applications. In addition, current techniques are incapable of producing polymers with true metallic electrical properties, and are incapable of producing practical organic/inorganic hybrid devices.

We have been working on an array of technologies to produce polymers with a wide range of electrical conductivities (from insulating to metallic), and to increase their compatibility with inorganic materials to form true organic/inorganic hybrid devices. Our high electrical conductivity samples have true metallic resistivity vs temperature trends while maintaining high flexibility and low thermal conductance.

Superconducting polymers

We aim to produce polymer based superconducting materials that have comparable critical temperature, critical current and critical magnetic field properties to that of conventional inorganic superconductors. In addition, these polymer based superconductors will be highly flexible, have low cost and use less material than superconductors currently being manufactured. This group of polymer based materials also have low thermal conductivity which assists in maintaining the low temperature environments in which superconductors must operate.

Additionally, this group of superconducting materials can be formed as finely divided conductors, or as discreet elements in polymer based microelectronics.

Advantages of organic superconductors:

Flexible conductive polymer
  • Highly flexible
  • Low production costs
  • Low material requirements
  • Low thermal conductivity
  • Roll-to-roll production
  • Finely divided conductors easily formed
  • Micron to submicron line width

We have recently met several of our proof-of-concept benchmarks, demonstrating that this class of materials has the ability to be competitive with their inorganic superconducting counterparts.

Near term proposed polymer superconductor capabilities
Our plan for the development of superconducting polymers over the next five years. Note that the inorganic superconductors of NiTi, Nb3Sn and Nb3Ge are displayed for reference.
