ACQUISITION OF A DISCOVERY LASER FLASH (DLF) DIFFUSIVITY SYSTEM FOR UNDERSTANDING THERMAL PROPERTIES OF 3D PRINTABLE POLYMER-NANOPARTICLE COMPOSITES
Abstract
A flash method is usually powerful in providing thermal characteristics. We propose to acquire a Discovery Laser Flash (DLF) diffusivity system to enhance our research and educational activities at Arizona State University (ASU) and the local community. Precisely measuring thermal conductivity, thermal diffusivity, and specific heat capacity can provide an in-depth understanding of heat transfer and energy management with broad applications in structural components, thermal packaging, microelectronics, optoelectronics, and thermoelectric devices to benefit the national defense. Our current research in composite studies includes textile engineering, coating technology, and additive manufacturing funded by federal agencies (e.g., ONR, NSF, AZ board) and industries (e.g., MECHnano, FACE Foundation). A systematic understanding of these composite materials thermal conductivity and their applications in heat dissipation and thermoelectric effects will generate fundamental knowledge in phonon transport, interfacial engineering, and nanoscale interactions. Characterizing thermal properties in anisotropic structures (e.g., fibers and coatings); combining the proposed DLF and our other resources (e.g., 3D printing, simulation, thermal imaging) will overcome these technical barriers. With the increasing demand and decreasing cost for this instrumentation, we expect an installation of DLF at ASU to allow sustainable and long-term research in composite engineering, material science, and advanced manufacturing areas. Sharing this facility across schools at ASU and with local industrial stakeholders will also enhance the education and workforce development for defense-relevant fields.
