Chat OnlineCharacterization of Viscoelasticity and Self‐Healing
Aug 18 2014 · The shear modulus of entangled networks increases with the deformation speed. This behavior confirms that the viscoelasticity is due to the dissociation and re‐association of non‐covalent bonding. The hydrogen bonding initiates the healing process and the diffusion of molecular chains strengthens the self‐healing ability.
