Revealed Architectures of Adsorbed Polymer Chains at Solid-Polymer Melt Interfaces
Peter Gin,Naisheng Jiang,Chen Liang,Takashi Taniguchi,Bulent Akgun,Bulent Akgun,Sushil K. Satija,Maya K. Endoh,Tadanori Koga +8 more
TL;DR: The lone flattened chains, which are uncovered by the additional prolonged solvent leaching (∼120 days), are reversibly densified with increasing temperature up to 150 °C, and it is postulate that the change in probabilities of the local chain conformations of polymer molecules is the origin of this densification process.

Impact of an irreversibly adsorbed layer on local viscosity of nanoconfined polymer melts.
Tadanori Koga,Naisheng Jiang,Peter Gin,Maya K. Endoh,Suresh Narayanan,Laurence Lurio,Shantanu Sinha +6 more
TL;DR: The results show the impact of a very thin adsorbed layer even without specific interactions of the polymer with the substrate, overcoming the effect of a surface mobile layer at the air-polymer interface and thereby resulting in a significant increase in the local viscosity as approaching the substrate interface.

TL;DR: In this paper, a series of bilayers composed of bottom hydrogenated polystyrene and top deuterated PS (d-PS) layers were prepared on Si substrates and a high-pressure neutron reflectivity (NR) technique was used to study the diffusive motion at the h-PS and d-PS interface as a function of the distance from the substrate interface.

TL;DR: In this paper, structural heterogeneity of recrystallized linear low-density polyethylene (LLDPE) films (25, 50, and 100 nm in thickness) in the direction normal to the surface, based on in situ gra...

Tadanori Koga,Peter Gin,Hiroki Yamaguchi,Maya K. Endoh,Mitsunori Asada,Levent Sendogdular,Motoyasu Kobayashi,Atsushi Takahara,Bulent Akgun,Bulent Akgun,Sushil K. Satija,Tomonari Sumi +11 more
TL;DR: In this article, the authors investigated swelling isotherms of solvophilic and solvophobic endgrafted/non-grafted polymer chains on solid substrates in supercritical carbon dioxide and supercritical ethane.
