Investigation on Curing Kinetics and Dielectric Properties of Nano-TiO_2/BMI/CE Composites

The non-isothermal curing kinetics of nano-TiO2/BMI/CE copolymers were studied by using the differential scanning calorimetry(DSC).The curing kinetics parameters of the modified system were obtained by Kissinger equation,Ozawa equation and Crane′s theory.The effects of different curing processes and post-process temperatures on the dielectric performances of nano-TiO2/BMI/CE system were investigated.The results show that better dielectric properties of microwave curing system are also compared with these of conventional heat curing system under the same content of nano-TiO2/BMI/CE.Dielectric properties of microwave curing nano-TiO2/BMI/CE composites get more increasing via controlling post-process temperatures and post-process time.
