Chain Conformations and Phase Separation in Polymer Solutions with Varying Solvent Quality [PDF]

open access: yesJournal of Polymer Science 59 (22), 2819-2831 (2021), 2021
Molecular dynamics simulations are used to investigate the conformations of a single polymer chain, represented by the Kremer-Grest bead-spring model, in a solution with a Lennard-Jones liquid as the solvent when the interaction strength between the polymer and solvent is varied.

Polymer Science: The Next Generation [PDF]

open access: yesMacromolecular Rapid Communications, 2012
Shiyong Liu The three of us have to confess we felt a bit over-age when the editors of the Macromolecular Journals approached us for editing a young investigators issue for Macromolecular Rapid Communications . Although we would prefer not to think about it, this forced us to admit that we are slowly reaching the senior scientist category (i.e., the ...

Mechanochemically accessing a challenging-to-synthesize depolymerizable polymer

open access: yesNature Communications, 2023
Polymers with low ceiling temperatures (Tc) are highly desirable as they can depolymerize under mild conditions, but they typically suffer from demanding synthetic conditions and poor stability.

The Next 100 Years of Polymer Science

open access: yesMacromolecular Chemistry and Physics, 2020
The year 2020 marks the 100th anniversary of the first article on polymerization, published by Hermann Staudinger. It is Staudinger who realized that polymers consist of long chains of covalently linked building blocks.

Polymer surface science

open access: yesThe Chemical Record, 2001
AbstractMolecular level studies of the structure and mechanical properties of polymer surfaces have been carried out by sum frequency generation (SFG) surface vibrational spectroscopy and atomic force microscopy (AFM). The surfaces of different grades of polyethylene and polypropylene have been characterized—including during the glass transition and ...

Intrinsically fluorescent polyureas toward conformation-assisted metamorphosis, discoloration and intracellular drug delivery

open access: yesNature Communications, 2022
Biomimetic materials are of interest but can often suffer from limitations caused by the non-native linkages used. Here, the authors report on the creation of amino acid constructed polyureas which can self-assemble into vesicles and nanotubes with ...

Isosorbide-Based Thermoplastic Polyurethane with Different Polyols and Soft/Hard Ratios

open access: yesAdvances in Polymer Technology, 2023
A series of isosorbide-based thermoplastic polyurethanes (ISB-TPUs) with different soft/hard ratios have been successfully step polymerized using individual two types of polycaprolactone diol (PCL) or poly (tetramethylene glycol) (PTMG) for soft segment ...
