CNT Polymer Composites for Optical & IR Transparent

"Triton team is responding to the Navy need for EMI shielding of both optical and IR transmitting transparencies, by proposing to develop carbon nanotubes (CNT) polymer composite coatings. For IR transparent EMI shielding we will disperse CNTs in sol-gelderived conducting inorganic polymers; for optically transparent EMI shielding we propose to disperse functionalized CNTs into conductive organic polymers, in both cases to achieve low electrical resistance (10 ohm/sq) with ~ 90 % transmissions. We basethis Proposal on Triton's successful experience in coating Navy polycarbonate windshields for anti-abrasion and anti-reflection, and in coating IR transmissive ALON flats with index matching polymers, combined with Triton team member nationally recognizedleadership in the development of functionalized CNTs, dispersed in both inorganic and organic conductive layers. In Phase I we will demonstrate transmissive CNT conductive layers for both windshields and IR windows. In Phase II, we will work with theNavy on specific optical or IR transmissive sub-systems and will fabricate coupons and/or subsystem components that will be tested for viability as new-generation transmissive EMI shielding materials. Triton is intending to develop innovative coatings thatare readily deployable onto a variety of substrate materials, which can be used for EMI shielding of canopies and IR windows. The innovation discussed in this proposal will allow for co
