Hydrophobic Polymers with Adherend Complexing Sidechains as Durable Aerospace Adhesives, Phase II

In support of NASA Aeronautics Research Mission Directorate and Aviation Safety Mission, NanoSonic has developed a series of moisture and corrosion mitigating, ultra-hydrophobic, environmentally tunable, nanophase separating adhesive modifiers and complementary high performance, wide service temperature range (-60C to 450C) structural adhesives. The smart nanostructured modifiers represent a significant discovery as the adhesion strength of our novel and commercial-off-the-shelf aerospace adhesives was increased by > 40% with inclusion of such systems upon aging in 100% relative humidity (RH), ten days, 140F. Of significant importance to manufacturability and dual-use commercialization, the novel modifying agents are inert, inorganic-organic, halogenated hybrid copolymers, and hence can be used with virtually any adhesive, paint or environmental aerospace materials systems. The inorganic poly(octahedral silsesquioxane) (POSS), fluorination and copolymer molecular weight can be synthetically engineered to complement any paste of film adhesive. The TRL of the novel adhesive system would be increased from 6-8 during Phase II.

This is a mature technology (TRL 7+) — the realistic path in is usually NASA's Technology Transfer Program: licensing an existing NASA patent, or a Space Act Agreement to use NASA facilities/expertise directly. NASA also runs a startup licensing program with no upfront fee for companies formed to commercialize a specific NASA technology.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
