Bisphenol-A diglycidyl ether (BADGE) and poly(propylene glycol) bis(2-amionpropyl ether) (JeffAmine D-230) were purchased from Sigma-Aldrich and used as received. BADGE/JeffAmine was thoroughly mixed stoichiometrically by volume (2.42 mL BADGE /1 mL JeffAmine) for at least 10 minutes with visual confirmation of homogeneity, followed by a degassing step of 5 minutes to remove any air bubbles, enabling reactive groups in each component to fully react with each other, resulting in an optimal cure. The resulting mixture was then deposited on different testing substrates.
