Abstract
Curing process and curing kinetics of ferrocenyl-terminated hyperbranched polyesters/epoxy resin systems were investigated by non-isothermal differential scanning calorimeter (DSC) under different heating-up rates. The apparent activation energy of the curing systems was calculated by Kissinger method and Ozawa method respectively. The reaction series were computed by means of Crane formula. Based on the data of DSC, the curing process of the curing systems was determined as 100°C2 h→140°C2 h→160°C1 h. After curing, the thermal properties of the composites were tested by thermo-gravimetry (TG) and DSC. It is found that the initial decomposition temperature is 287~330°C and the glass transition temperature is 105.29~130.27°C. Above results indicate that a little addition of HBPE-Fc could improve the thermal properties of epoxy resin systems obviously.
