Living Anionic Polymerization Using a Microfluidic Reactor

January 15, 2009
Author(s)
Thomas Q. Chastek, Kazunori Iida, Eric J. Amis, Michael J. Fasolka, Kathryn L. Beers, Jae H. Chun
Living anionic polymerizations were conducted within aluminum-polyimide microfluidic devices. Polymerizations of styrene in cyclohexane were carried out at various conditions, including elevated temperature (60 °C) and high monomer concentration (42 %, by

Measuring the Modulus of Hydrated Contact Lenses via Surface Wrinkling

April 6, 2008
Author(s)
Jun Y. Chung, Young Jong Lee, Peyton Hopson, Michael J. Fasolka, Christopher Stafford
One of the most important considerations in the evaluation of hydrogels for biomedical and contact lens applications is the elastic modulus. The elastic modulus relates to several important factors including flexibility, comfort, adhesion, swelling

High throughput adhesion testing using a modified edge lift-off test

February 17, 2008
Author(s)
Jiong Liu, Martin Chiang, Michael J. Fasolka, Christopher Stafford
The strength of an adhesively bonded joint depends on a host of factors such as surface treatment, roughness, materials properties, cure conditions and environmental variables. Therefore testing of adhesion within this large parameter space can be very

Measurement of Reactivity Ratios in Surface-Initiated Copolymerization

August 21, 2007
Author(s)
Derek L. Patton, Kirt A. Page, Chang Xu, Kirsten Genson, Michael J. Fasolka, Kathryn L. Beers
This work describes a new approach to measure monomer reactivity ratios from surface-initiated copolymerizations using x-ray photoelectron spectroscopy. Styrene/methyl methacrylate statistical copolymer brushes were prepared from various monomer feeds by

Surface Grafting of Polypyrrole onto Silicon Wafers

August 1, 2007
Author(s)
Daeson Sohn, Hyoseung Moon, Michael J. Fasolka, Naomi Eidelman, Sang-Mo Koo, Curt A. Richter, Eun S. Park, Joseph Kopanski, Eric J. Amis
A micromolding technique in capillaries was adapted to make uniform patterns of polypyrrole (Ppy), and the conductivities of the patterns were measured by direct contact IV curves and conductance AFM methods. Noncovalently bound Ppy patterns have high

NCMC Workshop ReportNCMC-10: Persistent Challenges in Combinatorial Materials Science

February 1, 2007
Author(s)
Michael J. Fasolka, Carol E. Laumeier, Kathryn L. Beers, Christopher M. Stafford
Tremendous advances in the development and application of combinatorial and high-throughput methods for materials research have been accomplished over the past 15 years. Despite these accomplishments, today s combinatorial materials science is met by some
