摘　　要：为了准确测定衬层/推进剂界面组成、分布特征及迁移规律,文中利用原位显微红外技术,测定了某些样品的衬层/推进剂界面法线方向不同位置的红外光谱,通过比较界面、推进剂、衬层的红外谱图,获得了界面法线方向基团和组成的空间变化信息,判断出组分在界面的分布、迁移方向和扩散层厚度;利用迁移方向和扩散层厚度能够判定界面粘接的优劣:从推进剂向衬层扩散的界面粘接性能差,反之粘接性能好;通过对不同老化时间样品的测试,获得了界面法线方向组成随时间变化的特征和扩散层厚度变化趋势。Using in-situ micro-ATR/FTIR technique, a series of IR spectrums of the different location along vertical direction to the interface between liner and propellant were obtained.The distribution and diffusion of the main composition and group were discussed by comparing the spectrums of propellant and liner.A judgment method which propellant and liner bonding interface is good or not was praposed by the direction and the thickness of diffusion ： the adhesive interface is good when the diffusion oecurr from liner to propellant and otherwise the adhesive interface is poor.Moreover,the IR spectrums of the different location along vertical direction to the interface between liner and propellant were tested and discussed with the varying aging time.
