Title: "Sensing stress in polymers using dynamic phosphorescent probe "

Abstract: Modern materials are designed to withstand various hazards in common everyday operation as failure to do so can often inflict severe losses in material performance. Aside from environmental resistance, the ability to sustain mechanical stress is a crucial feature of a robust material. The latter is particularly important for polymers, as they are often exposed to stress of alternating duration and magnitude. Quantifying the stress in polymers provides an invaluable aid in monitoring and preventing their failure. In this presentation i will tell you how one can use a dynamic phosphorescent copper complex incorporated into the main chain of polyurethanes to quantify stress and force distribution in polymer films. We will talk about the mechanism of sensor action and discuss its limitations.
 

Refreshments will be served afterwards. We hope to see you there!
