Adam N. Raegen

Experimental Polymer Physics
Postdoc with External Senior Fellow Ullrich Steiner


    Adam Raegen received his Bachelors of Science at Southern Oregon University in 2002. He then moved to Canada to pursue further studies at McMaster University, under the supervision of Prof. Kari Dalnoki-Veress in experimental polymer physics. He completed his Masters of Science in 2004 and continued on to his PhD, researching micromechanical and optical effects in thin polymer films. In December, 2008 he became a junior research fellow in the School for Soft Matter Research at FRIAS.

    Residual stresses due to preparation techniques and aging in thin polymer films

    Many techniques used to prepare polymer films result in residual stresses, the scale and type of which are dependant upon the precise conditions under which the films are made. While these stresses are present, the behaviour and morphology of the polymer can be greatly affected. We aim to investigate the type and scale of the residual stresses, and to observe the relaxation of these stresses as aging occurs, using differential scanning calorimetry, ellipsometry, optical microscopy, and atomic force microscopy.
