Influence of dispersant on gelation process of RF gels doped by titanium

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 (NaPO3)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．
