摘　　要：采用甲基笼型倍半硅氧烷(POSS)改性双酚A二氰酸酯(BADCy),研究了不同含量的POSS对BADCy结构及性能的影响,利用傅立叶变换红外光谱仪考察了BADCy/POSS杂化材料的反应性,研究了BADCy/POSS杂化材料的介电性能、热稳定性和耐湿热性能。结果表明,BADCy/POSS杂化材料具有比BADCy低的介电常数,有望用作高性能印刷线路板基体材料。Methyl polyhedral oligomeric silsesquioxane （POSS） was incorporated into bisphenol A dicyanate （BADCy） to prepare organic/inorganic hybrid materials. The effects of POSS content on the structure and properties of BADCy were studied. The reactivity of the hybrid materials was investigated by using Fourier transforms infrared. Besides,the dielectric properties,thermal stability and hot/wet resistance were investigated. Results indicated that POSS/BADCy hybrid materials having low dielectric constant was a promising PCB matrix material.
