Spinodal Dewetting of Thin Polymer Films

August 1, 1998
Author(s)
R H. Xie, Alamgir Karim, Jack F. Douglas, Charles C. Han, Robert A. Weiss
Dewetting of polystyrene (PS) films on a silicon substrate is investigated as a function of film thickness, h. We observe the nucleation of holes in the early stage of dewetting for relatively thick films (h > 100 {Angstrom}), as observed previously, but

Preparation and Characterization of Polymer/Dendrimer Blends Progress Report 2/24/97

June 1, 1998
Author(s)
Eric J. Amis, Barry J. Bauer, F I. Groehn, T J. Prosa, Da-Wei Liu, K A. Barnes, C L. Jackson, B D. Viers, Alamgir Karim, Jack F. Douglas
Dendrimer, dendrigraft, and hyperbranched solutions, blends, and interpenetrating polymer networks are characterized by small neutron and x-ray scattering, reflectivity, atomic force microscopy, and transmission electron microscopy.

NIST Meeting on Multicomponent Polymers and Polyelectrolytes

March 1, 1998
Author(s)
Jack F. Douglas
A joint meeting was held between the NIST Polymer Blends and Processing Group and ERATO. The purpose of the conference was to review progress made by the NIST and ERATO groups in experimental and theoretical aspects of phase separation in polymer blends

Colliding Self-Assembly Waves in Organosilane Monolayers

Author(s)
K Efimenko, Ali Ozcam, Jan Genzer, Daniel A. Fischer, Frederick R. Phelan Jr., Jack F. Douglas
Colliding autocatalytic wave-fronts of organosilane (OS) layer self-assembly are generated through the controlled positioning of sources of the volatile OS material at the edges of a silica wafer and through adjustment of the container dimensions in which
