Correlation between nanohole volume and mechanical properties of amine-cured epoxy resin blended withl poly(ethylene oxide)

A set of diglycidylether of bisphenol-A (DGEBA)/ 4,4′-diaminodiphenylmethane (DDM) epoxy matrix modified with poly(ethylene oxide) (PEO), pre-cured at two different temperatures, was examined by positron annihilation lifetime spectroscopy (PALS). The aim was to investigate the correlation between lo...
