Cracks and Crazes: On calculating the macroscopic fracture energy of glassy polymers from molecular simulations [PDF]
, 2001 We combine molecular dynamics simulations of deformations at the submicron scale with a continuum fracture mechanics calculation for the onset of crack propagation to predict the macroscopic fracture toughness of amorphous glassy polymers. Key ingredients in this multiscale approach are the elastic properties of polymer crazes and the stress at which ...

Significantly enhanced polymer thermal conductivity by confining effect through bilayer MoS2 Surfaces [PDF]
arXiv, 2021 The present work refers to a simulation study on nanoconfined polymers in polymer-MoS 2 nanocomposites as a function of MoS 2 -MoS 2 interlayer separation. We indeed apply reverse nonequlibrium molecular dynamics simulations (RNEMD) to investigate thermal conductivity of polyamide oligomers which is confined by MoS 2 bilayers.

Multiscale modelling of polymer structure and conformations in polymer nanocomposites: A Review [PDF]
arXiv, 2014 Over the past two decades polymer nanocomposites have received tremendous interest from industry and academia due to their advanced properties comparative to polymer blends. Many computational studies have revealed that the macroscopic properties of polymer nanocomposites depend strongly on the microscopic polymer structure and conformations.

Thermal Transport in Polymers: A Review [PDF]
arXiv, 2020 In this article, we review thermal transport in polymers with different morphologies from aligned fibers to bulk amorphous states. We survey early and recent efforts in engineering polymers with high thermal conductivity by fabricating polymers with large-scale molecular alignments.

Thermal conductivity of polymers and polymer nanocomposites [PDF]
arXiv, 2018 Polymers are widely used in industry and in our daily life because of their diverse functionality, light weight, low cost and excellent chemical stability. However, on some applications such as heat exchangers and electronic packaging, the low thermal conductivity of polymers is one of the major technological barriers.

Fine-tuned order-order phase transitions in giant surfactants via interfacial engineering
Giant, 2020 Thermotropic order-order phase transitions (OOTs) in block copolymers are not commonly observed in the strong segregation region. Phase separation of giant surfactants composed of hydrophilic molecular nanoparticles (MNPs) as heads and hydrophobic ...

Ground state properties of ferromagnetic metal/conjugated polymer interfaces [PDF]
, 2002 We theoretically investigate the ground state properties of ferromagnetic metal/conjugated polymer interfaces. The work is partially motivated by recent experiments in which injection of spin polarized electrons from ferromagnetic contacts into thin films of conjugated polymers was reported.

A review on the progress of polymer nanostructures with modulated morphologies and properties, using nonporous AAO templates [PDF]
arXiv, 2017 Polymers with the same chemical composition can provide different properties by reducing the dimension or simply by altering their nanostructure. Recent literature works report hundreds of examples of advances methods in the fabrication of polymer nanostructures accomplished following different approaches, soft lithography, self-assembly routes ...
