Abstract: This seminar will discuss topics at the beginning and the end of the material lifecycle. At the beginning of the material lifecycle, a new material manufacturing method will be discussed – morphogenic manufacturing, i.e. the generation of pattern and structure without machining or molding. Unstable reaction propagation during frontal ring-opening metathesis polymerization (FROMP) of dicyclopentadiene (DCPD) has been harnessed to generate spatially-resolved patterns in pDCPD resins. Autonomous color pattern development, pattern characterization and tunability, and applications to real-world systems will be discussed. The second section of this talk will center on the end of the material lifecycle. Cyclic poly(phthalaldehyde) (cPPA), an attractive transient material which rapidly depolymerizes upon activation, has been used to produce transient bulk materials. Topics will include advances in bulk processing of cPPA, mechanistic insights learned along the way, and the future of this stimulus-responsive polymer.
Biography: Currently a postdoctoral researcher in the Autonomous Materials Systems (AMS) Group at the University of Illinois, Adam Feinberg received a B.S. in Polymer Chemistry from the Rochester Institute of Technology in 2011 and a Ph.D. in Chemistry from the University of Rochester in 2017 under the direction of Prof. Joseph P. Dinnocenzo. As part of the AMS Group, and advised by Prof. Jeffrey S. Moore, Adam’s research combines mechanistic organic chemistry with materials science to create advanced functional plastics. Current research directions include new thermoset manufacturing methods for autonomous spatial functionalization and the development of transient materials with autonomous degradation function, the latter of which has been featured recently in the New York Times.
