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23.8kJ/m2,与CE相比提高了158%。
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 23.8kJ/m2,which increased 158% compared with that of neat CE,when the content of G-POSS was 7 phr.
