Abstract
The main aim of this research was the generation of new intelligent materials, in this case thermoreversible material, based on epoxy matrix modified with semi-crystalline block copolymers. In this study, the epoxy system based on a diglycidyl ether of bisphenol-A (DGEBA), was cured with a stoichiometric amount of an aromatic amine hardener, 4,4’-methylene bis (3-chloro-2,6-diethylaniline) (MCDEA). A diblock copolymer of polyethylene-b-poly(ethylene oxide) (PEOE) was used as self-assembly agent.Optical properties of the samples modified by addition of PEOE were studied by using transmission optical microscope (TOM) equipped with a hot stage. Additionally, morphology generated in the sample was studied by atomic force microscopy (AFM).
