中文摘要：

利用界面聚合技术制备了以不同单体为囊芯的新型感光材料光热敏微胶囊。借助于傅里叶红外光谱及原子力显微技术对不同单体的双键交联固化及固化产物的表面形貌进行了分析,利用热显影打印技术检测了光热敏微胶囊显影密度随曝光时间的变化。实验结果表明,不同单体的双键交联固化速度主要与单体官能度有关,并且单体固化产物的表面形貌与单体的双键含量有关,不同单体的固化速度和固化产物交联密度是影响光热敏微胶囊显影密度的主要因素。根据实验结果可以得出单体对显影密度的影响效果依次为TMPTA〉（PO3）TMPTA〉DPGDA。

英文摘要：

The light-thermal sensitive microcapsule is synthesized by interfacial polymerization method,which can act as novel information recording material,and the capsule core is distinguished by the encapsulated monomer.The surface topography of unencapsulated core material UV-curing is studied by atomic force microscopy,and the monomer curing property in microcapsule is analyzed by infrared spectroscopy technology,and the developing density of light-thermal sensitive microcapsule is detected by thermal imaging technology.The results show that curing speed of different monomer mainly depended on the function groups and surface topography of curing product have related on the contents of unsaturated CC bond in monomer.The curing speed of different monomer and cross-link density of curing product are the main factors effecting on the developing density of light-thermal sensitive microcapsule.Base on the experimental results,the effect of monomer on the developing density is ranked as： TMPTA（PO3）TMPTADPGDA.
