Designed-in molecular interactions lead to superior thermo-mechanical properties in nanocomposites [PDF]
, 2011 The effect of the nanofiller chemistry on the mechanical behaviour of thermoset polymer matrix nanocomposites is investigated. The interaction between a crosslinked polymer resin and the reinforcing nanofibers driven by their chemistry is revealed by ...

Morphology and dynamics of dense nanometric precursor lms of polymer melts [PDF]
, 2023 Nanometer-thick supported lms of polymer melts spontaneously form and spread around sessile droplets that are deposited on oxidized silicon wafers. At steady state, the lms become dense and adopt a uniform thickness which is equal to twice the gyration radius of the free polymer.

Effect of van der Waals interaction strength and nanocluster size on the dynamical and mechanical properties of 1,4-cis-polybutadiene melts [PDF]
, 2011 Using molecular dynamics simulations, we have investigated the effect of embedding nanoclusters of radius 3-7 Å on the dynamical and mechanical properties of 1,4-cispolybutadiene melts. To see the effect of polymer-nanocluster interaction strength on the

A Statistical Theory of cosolvent-induced coil-globule transitions in dilute polymer solution [PDF]
The Journal of Chemical Physics 141, 014902 (2014), 2014 We present a statistical model of a dilute polymer solution in good solvent in the presence of low-molecular weight cosolvent. We investigate the conformational changes of the polymer induced by a change of the cosolvent concentration and the type of interaction between the cosolvent and the polymer.

How Segmental Dynamics and Mesh Confinement Determine the Selective Diffusivity of Molecules in Crosslinked Dense Polymer Networks [PDF]
ACS Cent. Sci. 9 (2023) 508-518, 2023 The diffusion of molecules (penetrants) of variable size, shape, and chemistry through dense crosslinked polymer networks is a fundamental scientific problem that is broadly relevant in materials, polymer, physical and biological chemistry. Relevant applications include molecular separations in membranes, barrier materials for coatings, drug delivery ...

Electronic Properties of Vinylene-Linked Heterocyclic Conducting Polymers: Predictive Design and Rational Guidance from DFT Calculations [PDF]
Journal of Physical Chemistry C, 115, 18333 (2011), 2011 The band structure and electronic properties in a series of vinylene-linked heterocyclic conducting polymers are investigated using density functional theory (DFT). In order to accurately calculate electronic band gaps, we utilize hybrid functionals with fully periodic boundary conditions to understand the effect of chemical functionalization on the ...
