Stimuli-responsive Mechanical Properties in Polymer Glasses: Challenges and Opportunities for Defense Applications
The potential utility that responsive glasses provide in the areas of aeronautics, protection and unmanned systems was reviewed in this journal article. The article focused on two broad classes of stimuli, photo and thermal, to better illustrate the challenges and convey some of the potential in developing these materials for the often extreme operational environments of defense applications. Three response mechanisms were outlined to provide a range of mechanical behaviors on?demand. 1) Shape?changing functionalities which locally yield or soften the material to stimulate chain mobility. 2) Bond forming (or breaking) chemistries which increase (or decrease) the stiffness of the material. 3) Energy absorbing groups which convert the incoming stimuli into a spatially controlled heating and result in a designed softening of the material. Overall, continuing to develop responsive polymer glasses which respond rapidly and efficiently under low energy inputs will be critical for future defense applications.This article is protected by copyright.
