Interfacial irreversibly and loosely adsorbed layers abide by different evolution dynamics

X Li, X Lu - ACS Macro Letters, 2019 - ACS Publications
Within the interfacial region of the substrate, polymer chains can form the inner irreversibly
adsorbed and outer loosely adsorbed layers upon annealing. Owing to their different …

Metastable polymer adsorption dictates the dynamical gradients at interfaces

H Tian, C Bi, Z Li, C Wang, B Zuo - Macromolecules, 2023 - ACS Publications
Polymer adsorption proceeds through a wide variety of metastable states due to kinetic
constraints originating from the pinning of segments on solid interfaces, creating an …

Observing different dynamic behaviors of weakly and strongly adsorbed polystyrene chains at interfaces

X Li, X Han, X Wang, Z Chen, X Lu - Soft Matter, 2018 - pubs.rsc.org
Understanding the dynamic behavior of polymer chains adsorbed onto a solid surface is of
great importance for elucidating polymer–surface interactions. Here by using sum frequency …

Crystallization of thin polymer layers confined between two adsorbing walls

B Vanroy, M Wubbenhorst, S Napolitano - ACS macro letters, 2013 - ACS Publications
Confined at the nanoscale level, polymers crystallize much slower than in bulk, and in some
cases, the formation of ordered structure is inhibited within extremely long experimental time …

Temperature dependence of the dynamics and interfacial width in nanoconfined polymers via atomistic simulations

We present a detailed computational study on the temperature effect of the dynamics and
the interfacial width of unentangled cis-1, 4 polybutadiene linear chains confined between …

Evolution of irreversibly adsorbed layer promotes dewetting of polystyrene film on sapphire

X Li, X Lu - Macromolecules, 2018 - ACS Publications
Dewetting of a polymer thin film is directly correlated to the interface with the substrate. We
thus combined sum frequency generation (SFG) vibrational spectroscopy and laser …

Flattening process of polymer chains irreversibly adsorbed on a solid

Change in local conformation of polymer chains at film surface attached to solid surface

R Harada, D Kawaguchi, S Yamamoto, K Tanaka - Soft Matter, 2022 - pubs.rsc.org
Adhesion is a molecular event where polymer chains contact with a material surface to form
an interfacial layer. To obtain a better understanding of the adhesion on a molecular scale …

Non-equilibrium in adsorbed polymer layers
