The Influence of Solvent Quality on the Static Properties of a Linear Polymer: a Molecular Dynamics Study
نویسندگان
چکیده
We present molecular dynamics simulations of a polymer in a solvent of monomers. We have studied the influence of the “quality” of the solvent on the radius of gyration. This is modelled by varying the emp of a Lennard-Jones potential, which describes the interaction of the monomers with the polymer segments. Starting from an isolated chain (c,~= 0), the introduction of a very small interaction with the solvent causes a large decrease in the radius of gyration. A further increase of E,,,~ causes the radius of gyration to increase again.

Mechanical Properties of CNT-Reinforced Polymer Nano-composites: A Molecular Dynamics Study
Understanding the mechanism underlying the behavior of polymer-based nanocomposites requires investigation at the molecular level. In the current study, an atomistic simulation based on molecular dynamics was performed to characterize the mechanical properties of polycarbonate (PC) nanocomposites reinforced with single-walled armchair carbon nanotubes (SWCNT). The stiffness matrix and elastic p...

Mechanics of CNT-reinforced nano-cellular PMMA nanocomposites are investigated using coarse-grained molecular dynamics simulations. Firstly, static uniaxial stretching of bulk PMMA polymer is simulated and the results are compared with literature. Then, nano-cellular foams with different relative densities are constructed and subjected to static uniaxial stretching and obtained stress-strain cu...
متن کاملA macromolecule in a solvent: adaptive resolution molecular dynamics simulation.
The authors report adaptive resolution molecular dynamics simulations of a flexible linear polymer in solution. The solvent, i.e., a liquid of tetrahedral molecules, is represented within a certain radius from the polymer's center of mass with a high level of detail, while a lower coarse-grained resolution is used for the more distant solvent. The high resolution sphere moves with the polymer a...

Understanding the dynamics of polymer solutions in the semidilute regime is important not only from the point of view of advancing fundamental knowledge in polymer science but also from the point of view of technological applications. The behavior of semidilute polymer solutions varies significantly with concentration and solvent quality, which are reflected in the concentration driven crossove...
متن کاملIntroducing critical residues in the human prion protein and its Asp 178 Asn mutant by molecular dynamics simulation
The molecular dynamics (MD) simulation method is used to assess structural details for humanprion protein (hereafter PrPN) and its Asp178 Asn mutant (hereafter PrPm) which causes fatalfamilial insomnia disease. The results reveal that the flexibility and instability increase in PrPmcould be related to specific amino acids exposed to the solvent. Solvation free energy of PrPm is 20kjmot1nni2 mor...
