Initiated Chemical Vapor Deposition of Polymer Coatings and Membranes (Prof. Gupta - USC)


1)The October 23 monthly dinner lecture event is at a new location (Baylands Golf Links in Palo Alto); do not go to Michael's Restaurant at Shoreline in Mountain View out of habit.
2) Dinner will be buffet-style, so no meal selection is required for those registering for dinner.

Initiated Chemical Vapor Deposition of Polymer Coatings and Membranes

Prof. Malancha Gupta
Department of Chemical Engineering and Materials Science
University of Southern California


This talk will discuss the mechanism, capabilities, advantages, and applications of the initiated chemical vapor deposition (iCVD) process. The iCVD process is a solventless technique that can be used to deposit functional polymer coatings onto a variety of substrates. Monomer and initiator vapors are delivered continuously into a vacuum reactor. The initiator molecules are thermally cleaved into free radicals by a heated nichrome filament array and these free radicals diffuse to the substrate. Polymerization occurs on the surface of the substrate via a classical free radical mechanism. The solventless nature of the iCVD process allows for deposition of conformal hydrophilic and hydrophobic polymer coatings onto substrates with complex geometries including membranes and textiles. The ability to scale up the process for roll-to-roll manufacturing will be discussed. This talk will also discuss a new technique to make macroporous membranes by lowering the temperature of the substrate below the freezing point of the monomer. These macroporous membranes can be deposited onto porous substrates to create hierarchical porous-on-porous structures that enable improved filtration for water purification and sensor applications.

Speakers Background:

Malancha Gupta is currently an associate professor in the Mork Family Department of Chemical Engineering and Materials Science at the University of Southern California. She received her BS in chemical engineering from the Cooper Union in 2002 and her PhD in chemical engineering from MIT in 2007 under the guidance of Prof. Karen Gleason. She was a postdoctoral fellow with Prof. George Whitesides at Harvard University from 2007-2009. She received the Jack Munushian Early Career Chair in 2013 and the NSF CAREER award in 2013. Her research is focused on studying the chemical vapor deposition of functional polymers onto structured materials and liquid surfaces. She has mentored fourteen doctoral students and she has published 62 peer-reviewed manuscripts and 3 patents.
