Abstract |
Epoxidized soybean oil (ESO) was synthesized to improve the biodegradability and impact behaviors of the diglycidyl ether of bisphenol-A (DGEBA). The ESO was characterized using Fourier transform infrared (FT-IR) spectroscopy and gel permeation chromatography (GPC). DGEBA was blended with ESO contents from 10 to 50 wt% to obtain a modified network. DGEBA and the DGEBA/ESO 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). The impact behaviors of the DGEBA/ESO blends was studied by measuring the charpy impact energy. The morphologies were observed by scanning electron microscopy (SEM). The thermal property results confirmed that the crosslinking density of the epoxy networks decreased. The impact strength of the DGEBA/ESO blends was significantly improved with the addition of ESO owing to the reduced cross-linking density of the epoxy network. |
