Epoxidized linseed oil (ELO) was synthesized to improve the biodegradability and fracture toughness of the diglycidyl ether of bisphenol-A (DGEBA). The ELO was characterized using Fourier transform infrared (FT-IR) spectroscopy, gel permeation chromatography (GPC), and epoxy equivalent weight (EEW) tests. DGEBA was blended with ELO contents from 10 to 40 wt% to obtain a modified network. DGEBA and the DGEBA/ELO blends were characterized by their biodegradability, thermal properties, and fracture toughness. The thermal properties of the DGEBA/ELO blends were investigated using differential scanning calorimetry (DSC) and dynamic mechanical analysis (DMA). The fracture toughness of the DGEBA/ELO blends was studied by measuring the Izod impact strength and the critical stress intensity factor (KIC). The morphologies were observed by scanning electron microscopy (SEM). |
