The goal of the proposed STTR is to demonstrate the feasibility of using a rapid, automated spray layer by layer process, developed by the Hammond group in MIT's Department of Chemical Engineering, to create polyelectrolyte/carbon nanotube composites for Air Force applications at deposition rates superior to existing layer by layer techniques. This proposal will be led by NanoLab, Inc., a company with expertise in carbon nanotube production and functionalization, and composite manufacture. Dr. Paula Hammond's group at the Massachusetts Institute of Technology, who developed the spray LbL process, will serve as the academic research institution, providing optimization of LbL thin film nanocomposites, lab scale spray LbL expertise and access to equipment for mechanical characterization. NanoLab will also subcontract to Svaya Nanotechnologies, a company working to automate and scaleup the spray LbL technology platform, based on the technology originated at MIT. Together, the three companies are well suited to accomplish the goal of the effort, which is to demonstrate that high rate spraying of LbL composites can achieve mechanical properties on par with or exceeding the best dipped LbL composite systems. BENEFIT: Missile skins & Structural Components are perhaps the largest opportunity for the DoD. These high strength carbon nanotube-based composites have the potential to replace traditional materials with lower specific properties. Coatings and transparent conductors are other areas where the unique mechanical and electrical properties of the CNT nanocomposites have the potential to upend existing products and create new markets. Nanotube based composites have broad applicability in a number of areas. We also see potential electrochemical applications for these materials as electrodes for supercapacitors, fuel cells, and batteries.
