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

The 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 ...

Mechanochemically accessing a challenging-to-synthesize depolymerizable polymer
Nature 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.

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

How to derive and parameterize effective potentials in colloid-polymer mixtures [PDF]
Macromolecules 35, 1860 (2002), 2002 Polymer chains in colloid-polymer mixtures can be coarse-grained by replacing them with single soft particles interacting via effective polymer-polymer and polymer-colloid pair potentials. Here we describe in detail how Ornstein-Zernike inversion techniques, originally developed for atomic and molecular fluids, can be generalized to complex fluids and ...
