A predictive multiscale computational framework has been proposed to study the viscoelastic properties of polymeric materials. Using the Inverse Boltzmann Method, both the …
Addition of nanoparticles into a polymer matrix can significantly alter its structure, dynamics as well as viscosity. In this paper, we study the structural, dynamical and viscous behaviors …
Using a benchtop NMR spectrometer, we performed proton multiple-quantum NMR experiments to study the dynamics of well-entangled linear poly (butadiene), poly …
A recently proposed hierarchical triple-scale simulation methodology (Behbahani et al., Macromolecules, 2021, 54, 2740–2762) is applied to cis-1, 4 polyisoprene melts of a broad …
In this paper, the polymer chain packing and primitive path (PP) network of uncrosslinked and crosslinked cis-polyisoprene (PI) polymer are analyzed upon employing coarse-grained …
