| 摘 要： | 通过熔融共混法制备了高韧性氰酸酯树脂(CE)/八环氧基笼型倍半硅氧烷(G POSS)杂化材料，通过傅里叶变换红外光谱分析仪（FTIR）、扫描电子显微镜（SEM）和差示扫描量热仪（DSC）等方法对其结构和性能进行了表征。结果表明， G POSS能提高CE的固化反应速率，增加材料的韧性；当 G POSS的含量为7 份时，改性树脂固化物的冲击强度最高，达到238 kJ/m2，与CE相比提高了158 %。

| Abstract: | A hybrid material was prepared via melt blending method from glycidyl polyhedral oligomeric silsesquioxane (G POSS) and bisphenol A dicyanate ester (CE). The structure of the hybrid was characterized by Fourier transform infrared spectrometer (FTIR), scanning electron microscope (SEM), and its properties were tested. It was revealed that the G POSS could obviously accelerate the curing reaction of the resin. The toughness of the matrix was improved by G POSS. The impact strength of G POSS/CE hybrid materials was 238 kJ/m2, which increased 158 % compared with that of neat CE, when the content of G POSS was 7 phr. |
