Spring 2017 Seminar Series

PPSM sponsors a series of seminars covering a broad range of topics of general interest to the polymer community, featuring speakers from both on and off campus. [LIST OF PPSM SEMINARS 1986 to PRESENT] We invite the polymer community at MIT and elsewhere to participate. For further information, contact Professor Jeremiah Johnson at jaj2109@mit.edu. All talks take place on Wednesdays.

FINAL POLYMER SEMINAR FOR SPRING 2017:

“Deposition, mechanics and phase behavior of polyelectrolyte complex films”

Wednesday May 17th

Prof. Kenneth R. Shull
Department of Materials Science and Engineering
Northwestern University

ABSTRACT: Polyelectrolyte complexes made from the mixtures of oppositely charged polymers exhibit the full range of behaviors from low viscosity, polymer solutions to rigid, elastic solids. Our focus on this talk is largely on the solid-like behavior of these materials, using the quartz crystal microbalance as a high-frequency rheometer. We also show how electrochemically-induced pH changes can control he deposition process, leading to a simple and powerful method for surface modification.
