Coal Structure - an overview ScienceDirect Topics

If the internal hydrogen bonds are destroyed, either by chemical derivatization or by complexation with a solvent that is a strong hydrogen bond acceptor, the properties of coals change enormously. The network is now quite flexible, and the coal is a rubbery solid, which is no longer brittle. Diffusion rates are enormously enhanced.

2021-4-10  The feature of transitional coal differs from the brittle and ductile coal, as the transitional coal has an obvious yielding platform in the pre-peak and post-peak. If the post-peak modulus M is defined by the ratio of increments of stress to strain, it can derive that the smaller value in M represents a higher level of plasticity.
