Triple Detection System for Characterization of Depolymerizable Polymers
Abstract
This proposal seeks support for purchasing a Wyatt triple detection system to append to an existing gel permeation chromatograph (GPC) for characterizing synthetic polymers. The triple detection system consists of (i) an Optilab TrEX refractometer, (ii) a Viscostar II viscometer, and (iii) a Dawn Heleos 8 multi-angle light scattering detector. Combining these instruments with our existing GPC will give us the capability to (i) determine the absolute molecular weights of polymers that we are designing in our ARO- and DTRA-sponsored efforts, which is essential for correlating small molecular changes of the polymers to changes in the macroscopic properties of materials; (ii) characterize physical properties of the polymers (namely, the radius of gyration and hydrodynamic radius); and (iii) characterize the molecular weight and branching density of branched polymeric systems. Additionally, the triple detection system also will (i) accelerate current collaborative efforts with Ayusman Sens group (a DTRA-sponsored project) at the Pennsylvania State University; (ii) position graduate students and postdoctoral fellows conducting the research at the forefront of polymer characterization techniques; and (iii) expose undergraduate chemistry students (who enroll in an existing advanced organic laboratory course) to aspects of polymer chemistry and state of-the-art polymer characterization.
