| 摘 要： | 以间苯二酚、甲醛和经分散的纳米钛粉为反应前体，利用物理掺杂方法研究了掺钛RF凝胶的制备工艺，并在凝胶过程中以zeta电位 粒径分布测试仪对溶液的粒径分布进行分析测试。实验发现六偏磷酸钠对纳米钛粉的分散性最好，掺杂后凝胶时间明显缩短；分散剂种类和用量对凝胶时间有较大影响，其用量为纳米钛粉量的50~100倍为宜。

| Abstract: | The metal doped resorcinol-formaldehyde gels are important target materials in inertial confinement fusion research,especially for application foreground of low-temperature freeze target research. In this paper ,resorcinol,formaldehyde and titanium nanoparticles are used as reactants, titanium nanoparticles are doped into RF gels successfully by physic method. In gelation process, the particle-diameter distributions are measured by zetasizer. The result indicates that the best dispersant for titanium nanoparticles is (NaPO_3)_6 and after doped, gelation time is shortened.The variety and dosage of dispersamts can influce the gelation time. The dosage of dispersomts should be as 50～100 times as that of titanium nanoparticles. |
