Broadband Molecular Dynamics for Kinetic Aging Research of Polymeric Materials
Abstract
The requested instrumentation combines Dynamic Mechanical Analysis (DMA) and Dielectric Thermal Analysis (DETA) instruments to examine broadband molecular dynamics of polymeric materials. The instruments can be used separately or in combination. The modular instrument designs assure long-term viability and flexibility. Each instrument separately offers unique and superior capabilities. The Anton-Paar MCR 702 Twindrive is the first DMA to offer linear and radial motors that can be operated individually or in tandem. Omicron Labs Spectano 100 is the first Dielectric Analyzer to offer both frequency and time domain analyses in one instrument. The availability of simultaneous data from both instruments aids effective interpretation. In combination, the system will provide information that is not accessible elsewhere.Molecular structure and dynamics are key to examining rheological properties of many polymers,metamaterials, nanocomposites, and biomaterials. The instrumentation can advance collection of broadband data for materials research as well as provide high fidelity data for modeling and design codes. Application of these instruments to characterizing kinetic aging of polymers will be immediately pursued. The University of Texas at Austin recognizes and encourages the value of teaching students through research. The opportunities to work with characterization techniques, state-of-art instruments, and raw data analysis are significant teaching tools. The requested instrumentation will be accessible to faculty, staff, students and collaborating researchers at TheUniversity.
