Protein Resistance Driven by Polymer Nanoarchitecture Open
We report that the nanometer-scale architecture of polymer chains plays a crucial role in its protein resistant property over surface chemistry. Protein-repellent (noncharged), few nanometer thick polymer layers were designed with homopoly…

“Structurally Neutral” Densely Packed Homopolymer-Adsorbed Chains for Directed Self-Assembly of Block Copolymer Thin Films Open
In this work adsorbed chains composed of one of the constituent blocks can be used as a new surface modification approach to induce perpendicularly oriented lamellar microdomains in block copolymer thin films. A nearly symmetric polystyren…

Structure-induced switching of interpolymer adhesion at a solid–polymer melt interface Open
We demonstrate the mechanism of “molecular welding” at the polymer–solid interface.

Chain Conformation near the Buried Interface in Nanoparticle-Stabilized Polymer Thin Films Open
It is known that when nanoparticles are added to polymer thin films, they often migrate to the film-substrate interface and form an “immobile interfacial layer”, which has been believed as the origin of suppression of dewetting. We here re…

Novel Effects of Compressed CO<sub>2</sub> Molecules on Structural Ordering and Charge Transport in Conjugated Poly(3-hexylthiophene) Thin Films Open
We report the effects of compressed CO2 molecules as a novel plasticization agent for poly(3-hexylthiophene) (P3HT)-conjugated polymer thin films. In situ neutron reflectivity experiments demonstrated the excess sorption of CO2 molecules i…
