Epoxy Toughening with Nano-Sized Amphiphilic Block Copolymer Micelles
A model diglycidyl ether of bisphenol A (DGEBA) epoxy resin was modified with a poly(ethylene-alt-propylene)-b-poly(ethylene oxide) (PEP-PEO) block copolymer to improve fracture toughness. Two distinct nanoscaled morphologies were achieved in the cured systems: spherical micelles [...]
