Overview of Technology

Polyarylene networks for applications such as thin film dielectrics, light emitting diodes and as precursors to carbon structures

Background on Technology

Although much has been published on BODA (bis-ortho-diynlarene) derived polymers and carbon structures, upon pyrolysis, the use of these precursors to produce carbon-carbon composites is unknown.

Technology Description

Polyarylene networks are prepared via the thermal cyclopolymerization of BODA monomers affording intermediate resins which are processed via melting and thermally cured. BODA monomers are prepared in 3 steps from commercial bis-phenols and undergo radical mediated Bergman cyclization and overall step-growth propagation to variable molecular weight reactive resin intermediates. After thermal polymerization/copolymerization with other MODA monomers to achieve desired rheological properties for processing via extrusion, infusion, coating or micro/nano-molding and final cure, the resulting polyarylene networks are useful for applications such as thin film dielectrics, light emitting diodes and as precursors to carbon structures as this invention discloses.

Applications

This invention can be applied to Polymer matrix composites (PMC), carbon carbon composites (CCC) for extreme environment stability. Some industries that this technology would benefit include Hypersonic aircraft, missiles, other high-speed atmosphere, LEO or space vehicles. Some ground-based automotive and other high performance carbon applications are also relevant.

Opportunity

This technology is in the Pre-Alpha Prototype stage and would benefit from assistance with further development and testing opportunities.
