Mechanochemically-Active Polymer Composites

Abstract

Progress during the prior funding period includes understanding of fracture-induced mechanophore activation, development of a new computational model for predicting mechanochemical phenomena, and the development of new analytical techniques to study mechanochemistry. These studies are making it possible to compare the theoretical and experimental threshold forces that induce mechanochemistry. Other mechanophore advances include a detailed structure-activity relationship for a series of cyclobutane mechanophores and force-induced Diels-Alder cycloreversions. Experimental methods have been developed to characterize the mechanisms of macroscopic force transfer from a bulk solid polymer to linked mechanophores based on studies that address mechanochemical activation under tensile loading, shear, and fracture behavior.
