4,4,-Bismaleimidodiphenylmethane (BMIPM)/O,O,-diallylbisphenol
A (BA) system was modified by organic rectorite (OREC) to develop a novel
BMI/BA/OREC nanocomposite. The effect of OREC on the viscosity and reactivity
of BMIPM/BA system was investigated. The mechanical properties of BMIPM/BA/OREC
composites such as the flexural and impact strength were evaluated. The
morphology of cured BMIPM/BA/OREC systems was investigated by X-ray diffraction (XRD), transmission electron
microscopy (TEM), and scanning electron microscopy (SEM). The hot water resistance
of BMIPM/BA/OREC systems was discussed. The thermal property of BMIPM/BA/OREC
systems was investigated using thermogravimetric analysis (TGA). The dynamic
mechanical properties of BMIPM/BA/OREC systems were also measured. Results show
that the addition of OREC has a significant influence on the reactivity of the
BMIPM/BA system. Proper content of OREC can improve the flexural strength,
impact strength, and hot water resistance of a BMIPM/BA system. The addition of
OREC cannot decrease the thermal degradation temperature of cured BMIPM/BA system
with a slight sacrifice of the glass transition temperature (Tg).
