Abstract The principle of the r eact ion abo ut curing system of epox y resin by catio nic initiators was discussed, the efficiency of lanthanide triflates in the system of DGEBA、DGEBA/C-BL、DGEBA/ MCB、DGEBA/ MA、DGEBA/ PC was summarized. The selection principle of the curing agent was analyzed. And the application of lanthanide triflates in the DGEBA/ PA was prospected.
