|Abstract||Nanoengineered surfaces offer a variety of possibilities to manipulate fluid transport and enhance heat dissipation characteristics. The nanoscopic structures (nano, hierarchical structured arrays) can be fabricated to create superhydrophilic and superhydrophobic surfaces with unique transport properties by various techniques. The formed surfaces have unique properties for instance, adhere or release from surfaces in either wet or dry conditions or both, endure wear or resist hostile corrosive environments, manage heat transfer, manage incident light. Here, at university of Arkansas at Little Rock, We developed a cost-effective and high-throughput fabrication method using nanoscopic structure arrays at various geometries on solid substrates. This is done by preparing a surface of a substrate of a first material, modifying the surface through an etching process to generate a plurality of nucleation sites in an array; forming, by using glancing angle deposition, a plurality of nano-rods of a second material and each at a respective one of the plurality of nucleation sites in the array; and depositing a conformal coating on the plurality of nano-rods.|
