AbstractPresently, there is a pressing need from U.S. Army in developing metal nano-coated graphite microfibers, which will be used for military applications such as infrared threat sensor countermeasures because they are excellent attenuators in the infrared region of the electromagnetic spectrum. The metal nano-coatings around graphite microfibers are desired to have high electrical conductivity, be with the thickness less than 100 nm, and simultaneously can be produced at a low cost. However, there is not a cost-effective processing method available that is capable of depositing a metal nano-coating meeting the above characteristics. Therefore, in this proposed research program, Aegis technology will: (1) Develop and demonstrate a novel nano-coating method based on electroless nano-coating technique to generate a highly conductive metal nano-layer (less than 100 nm) around graphite microfibers; (2) Identify the underlying technical issues that govern the fabrication and performance of the nano-coating synthesized; and (3) Use this knowledge to design and manufacture such highly conductive metal nano-coatings around graphite microfibers that exhibit the infrared attenuation required by Army. The anticipated technological impact of the proposed research program is the design, development and implementation of a commercially viable nano-coating fabrication method to produce highly conductive metal nano-coating that can be integrated into existing military and industrial applications and lead to numerous new applications as well.
