Boron Nitride Nanotube and Carbon Nanotube Continuous Yarns and Tapes

AFFILIATION:   American Boronite Corporation, Burlington, Massachusetts, United States


Track: Advanced Materials
Area: Structural & Multifunctional Materials
Tech Readiness: TRL 6

Tech Brief: We use a proprietary, scalable gas phase pyrolysis to continuously synthesis boron nitride and carbon nanotube tape and yarn at high growth rates. These materials have multifunctional capabilities that provide a competitive advantage as structural materials, for ESI and EMI shielding, water filters, and for flexible electronics and batteries.


Value Proposition: 1. Multifunction continuous BNNT and CNT fibers and tapes provide property compositions that reduce cost and provide broad flexibility to designers. For example, many NASA satellites are made of aluminum (weak, low modulus and radiation damage prone). If these were made of boron-nitride then they would be many times stronger, much lighter, stiffer and would provide radiation protection. They would also likely be resistant to atomic oxygen, to high energy electrons, and provide unexpected vibration damping- desirable on a satellite.. 2. The Juno satellite uses CNT materials invented by the author to withstand the intense radiation environment around Jupiter. 3. Composite strength using CNTs and BNNTs might eventually approach 3 GPa with yarns more than twice this number. 4. Cables made of CNT shielding, BNNT dielectric and BNNT composites would be up to 1/3 lighter, fire resistant and can carry very high power. 5. Ampacitiy of CNT cables in vacuum exceeds 10**9 A/m2 6. The tailorable band gap of BNNT suggest a profoundly new material for multijunction flexible solar cells with unheard of power to weight ratios.
