Resumen:
Recently, considerable attention has been devoted to the synthesis of fluorine-containing polymers. Because surface properties depend critically upon the molecular structure and composition at the surface in question, the goal of bulk modification is generally the design of a polymer with a specific surface structure.  It is well known that the low surface free energy of fluorinated species provides a thermodynamic driving force for migration to the air-polymer interface . The aim of our investigation is to analyze the effects of adding different amounts of fluorinated thermoplastics (FT) on several properties of epoxy networks. For this purpose, we report different ways of modifying a thermosetting material based on a diglycidyl ether of bisphenol A (DGEBA) and an aromatic diamine (4,4´-methylenebis(3-chloro 2,6-diethylaniline, MCDEA, Aldrich).        Many characterization studies have been performed on the materials obtained, such as optical, thermal and surface properties.
