Block copolymer thin films: pattern formation and phase behavior

PF Green, R Limary - Advances in Colloid and interface Science, 2001 - Elsevier
During the last decade, research on thin, sub-micron thick, block copolymer films was
devoted toward understanding and controlling microstructural and topographical features at …

Templating of thin films induced by dewetting on patterned surfaces

K Kargupta, A Sharma - Physical Review Letters, 2001 - APS
The instability, dynamics, and morphological transitions of patterns in thin liquid films on
chemically heterogeneous striped surfaces are investigated based on 3D nonlinear …

Dynamic density functional study on the structure of thin polymer blend films with a free surface

H Morita, T Kawakatsu, M Doi - Macromolecules, 2001 - ACS Publications
Using the dynamic density functional method, we studied the structural evolution of a thin
film of polymer blends placed between the solid substrate and free surface. We observed …

Two new approaches for patterning polymer films using templates prepared by microcontact printing

P Ghosh, WM Lackowski, RM Crooks - Macromolecules, 2001 - ACS Publications
Two new methods for preparing micron-scale patterns of hyperbranched polymer films are
reported. Both approaches rely on passivation of a reactive surface by microcontact printing …

Surface phase diagrams for wetting on heterogenous substrates

C Rascón, AO Parry - The Journal of Chemical Physics, 2001 - pubs.aip.org

separation of thin polymer blend films in two-dimensional models. The focus of our work is …

Self-organized cohesion of organic molecular dots on chemically patterned surface

H Hieda, N Gemma, K Naito - Japanese Journal of Applied …, 2001 - iopscience.iop.org
Self-organized pattern formation of nonpolymeric amorphous molecules on substrates,
which have nanometer-scale chemical patterns, is demonstrated. It is observed that droplet …

Imaging phase-separated domains in conducting polymer blend films with near-field scanning optical microscopy

[PDF][PDF] Tribological properties of topographically structured polymer films

MR Dusseiller - 2001 - research-collection.ethz.ch
It was the goal of this study to reproduce results, obtained in the SFA, for a topographically
structured polymer surface sliding on a flat counterface, using a state-of-the-art tribometer …
