Description:About the Seminar:\n\nThe covalent attachment of polymers has e
 merged as a powerful strategy for the preparation of multi-functional surf
 aces. Patterned\, surface-grafted polymer brushes provide spatial control 
 over a variety of physical properties and allow for fabrication of ‘inte
 lligent’ substrates which selectively adapt to their environment. This p
 resentation describes recent advances in our group in using photolithograp
 hy to produce topographically and chemically patterned polymer brush surfa
 ces via surface-initiated (SI) photoinduced electron/energy transfer (PET)
  reversible addition–fragmentation chain transfer (RAFT) polymerization.
  Using this oxygen tolerant approach\, organic light emitting diodes (OLED
 s)\, anti-microbial surfaces\, and anti-fogging coatings are engineered to
  highlight facile pathways towards advanced functional surfaces. Oxygen to
 lerance\, mild reaction conditions\, and the use of visible light make thi
 s approach user-friendly in its application for the design of patterned an
 d functional organic thin films.\n\nAbout the Speaker:\n\nChristian receiv
 ed his Diploma in Polymer and Colloidal Chemistry from the University of B
 ayreuth (Germany)\, before working for Prof. Alexander Böker at the DWI -
  Leibniz Institute for Interactive Materials (RWTH Aachen University\, Ger
 many). In 2013\, he graduated summa cum laude and was awarded the Borcherâ
 €™s Medal for his Ph.D. thesis on block copolymers in electric fields. He 
 was then hosted by Profs. Edward J. Kramer and Craig J. Hawker at the Univ
 ersity of California\, Santa Barbara (USA) as an Alexander-von-Humboldt Fe
 odor-Lynen Postdoctoral Fellow. Christian is currently the Thomas K. Heple
 r Early Career Professor in Chemical Engineering at the Pennsylvania State
  University and holds courtesy appointments in the Chemistry Department an
 d the Materials Science and Engineering Department. 4:00 pm
