Elastic modulus and yield strength of semicrystalline polymers with bond disorder are higher than in atomic crystals
Andrea Giuntoli, Dino Leporini
We perform thorough molecular-dynamics simulations to compare elasticity and yielding of atomic crystals and model semicrystalline polymers, the latter characterized by very simila…
Effect of nematic ordering on the elasticity and yielding in disordered polymeric solids
Nicola Calonaci, Andrea Giuntoli, Sebastiano Bernini +1
The relation between elasticity and yielding is investigated in a model polymer solid by Molecular-Dynamics simulations. By changing the bending stiffness of the chain and the bond…
Bond disorder, frustration and polymorphism in the spontaneous crystallization of a polymer melt
Andrea Giuntoli, Sebastiano Bernini, Dino Leporini
The isothermal, isobaric spontaneous crystallization of a supercooled polymer melt is investigated by MD simulation of an ensemble of fully-flexible linear chains. Frustration is i…
Molecular layers in thin supported films exhibit the same scaling as the bulk between slow relaxation and vibrational dynamics
Matteo Becchi, Andrea Giuntoli, Dino Leporini
We perform molecular dynamics simulations of a supported molecular thin film. By varying thickness and temperature, we observe anisotropic mobility as well as strong gradients of b…
