The epoxidized linseed oils (ELO) was synthesized and characterized. The ELO was blended with the epoxy resins (diglycidylether of bisphenol-A, DGEBA) to obtain the modified network having ELO content from 0 to 40 wt.%. The neat epoxy resins and modified networks were characterized by the thermal and mechanical properties. The thermal properties of the DGEBA/ELO blends were investigated using several techniques and the mechanical properties of the DGEBA/ELO blends were studied by means of measurements of the Izod impact strength. In the result, the Izod impact strength of the DGEBA/ELO blends was significantly improved with the addition of ELO, owing to high intermolecular interactions in the DGEBA/ELO blends. |
