Protective Superhydrophobic Coatings for Underwater Electronics

Sensitive and expensive electronic equipment used in marine environments are generally subjected to harsh extremes. Component lifetimes are typically extended by physical isolation using bags, hard containers or with conformal impermeable coatings. However, over time, protective measures become compromised, the resulting exposure causing corrosion and short circuit-driven malfunctions. There is a need for advanced technologies that effectively protect electronics and sensitive components used in marine environments. Technologies can further benefit from efficient heat dissipation (high thermal conductivity), electrical insulation (low electrical conductivity) and compatibility with the interconnectivity of electronic assemblies. SOCOM has identified a responsive and promising nanotechnology-derived platform: protective superhydrophobic coatings. In response to the need for a feasibility study, an exhaustive evaluation of existing superhydrophobic coating technologies (materials and methods) is proposed herein. Technologies will be evaluated vis--vis Lynntech"s own superhydrophobic coatings technology, derived from various polymer/nanoparticle composites. Studies proposed will thoroughly evaluate coating technologies and identify promising options for both salt and fresh water applications. Feasibility studies are designed to predict coating performance at different depths (varying pressure and temperature). Risks and potential payoffs will be addressed and the option that best achieves the objective of this technology pursuit will be identified and recommended for further development.
