The wetting of the planar interface between air saturated with octane vapor and an aqueous solution by octane is investigated by ellipsometry and interfacial tension measurements. The interfacial interactions are varied through the concentration of the uncharged solute (glucose). We observe abrupt and continuous increases of the octane coverage with growing solute concentration. This we attribu...

To fully understand the polymer-filler interfacial interaction mechanism, we use a coarse-grained molecular dynamics simulation to mainly investigate the interfacial dynamic properties by tuning the polymer-filler interaction, temperature, chain length, volume fraction of filler, and size and shape of filler. The polymer beads around the filler exhibit an obvious layering behavior and a gradien...

in this paper, we studied effect of different parameters including density, viscosity, interfacial tension and solute transfer concentration on phase inversion hold-up. the results showed that change in phase density ratio had no effect on phase inversion hold-up. it also disclosed that the phase viscosity ratio was the most effective parameter affecting phase inversion hold-up and each phase h...

We study the phase behavior and the interfacial tension of the screened Coulomb (Yukawa) restricted primitive model (YRPM) of oppositely charged hard spheres with diameter sigma using Monte Carlo simulations. We determine the gas-liquid and gas-solid phase transitions using free energy calculations and grand-canonical Monte Carlo simulations for varying inverse Debye screening length kappa. We ...

Helical fibers in nanoscale have been of increasing interest due to their unique characteristics. To explore the effect of polymer type on helical fiber formation, three polymer systems, Poly(m-phenylene isophthalamide) (Nomex)/polyurethane (TPU), polystyrene (PS)/TPU and polyacrylonitril (PAN)/TPU are used to fabricate helical nanofibers via co-electrospinning. Differential scanning calorimetr...

We adopted molecular dynamics simulation to study the conductive property of nanorod-filled polymer nanocomposites by focusing on the effects of the interfacial interaction, aspect ratio of the fillers, external shear field, filler-filler interaction and temperature. The variation of the percolation threshold is anti N-type with increasing interfacial interaction. It decreases with an increase ...
