New Method to Acquire Chemomechanical Parameters of Diverse Chemical Reactions.

摘要

The focus of our AFOSR-supported research has been to develop the theoretical and experimental methods the following question: How does the kinetic (or thermodynamic) stability of a localized reactive site in a long inert polymer changes as the polymer is stretched. This question has preoccupied polymer scientists since at least 1940 and the lack of models to answer it for an arbitrary reactive site, i.e., to predict changes in kinetic or thermodynamic stability of various monomers, is emerging as the major roadblock to efficient design of stress-responsive and actuating polymers, the dynamics of viscoelastic flows of polymers and the design of new (smart) delivery and storage materials.
