采用差示扫描量热法（DSC）、x射线衍射法（XRD）和红外光谱法（IR）研究了聚m-基己二酰胺（MXD6）与纳米二氧化硅（SNPs）复合材料的界面结构。复合材料的DSC曲线显示，在0 ~ 40℃时，复合材料的比热变化类似于玻璃化转变行为（亚t -g），且亚t -g随snp质量分数的增加而减小。随着SNPs质量分数的增加，结晶温度（T-c）降低，XRD峰变尖锐。红外光谱表明，SNPs的加入削弱了MXD6链间的氢键。(C) 2012，日本应用物理学会
Interfacial structure of composites of poly(m-xylylen adipamide) (MXD6) and silica nano-particles (SNPs) was investigated by differential scanning calorimetry (DSC), X-ray diffractometry (XRD), and infrared (IR) spectroscopy. In the DSC curves of the composites, changes in specific heat similar to a glass transition behavior (sub-T-g) were detected at 0-40 degrees C, and sub-T-g decreased with the increase in the weight fraction of SNPs. Crystallization temperature (T-c) decreased, and XRD peaks became sharper with the increase in the weight fraction of SNPs. The IR spectra suggest that the hydrogen bonds between MXD6 chains were weakened by the addition of SNPs. (C) 2012 The Japan Society of Applied Physics
