In this work, the synthesis of epoxidized castor oil (ECO) and to modification of epoxy resins. The characterizations of ECO were studied through the measurement of FT-IR and NMR analyses. The thermal properties of the composites were studied through measurements of DSC and TGA. As a result, thermal stability and glass transition temperature of the blends were slightly decreased with increasing the ECO content. This might be caused by the reduction of cross-linking density of the epoxy network, which could be attributed to the incomplete curing reaction in the blend systems. |
