Intermolecular interactions on amine-cured epoxy matrices with different crosslink densities. influence on the hole and specific volumes and the mechanical behavior

The architecture of an epoxy matrix was modified by curing the resin with mono-/diamine mixtures having identical chemical structures. Both hole volume and specific volume variations were studied by positron annihilation lifetime spec-troscopy and pressure-volume-temperature/density measurements, re...
