The temperature dependent mechanical properties of PMR-15 polyimide are successfully measured through a novel high temperature nanoindentation technique. A sharp-tipped Berkovich nanoindenter equipped with hot-stage heating system was used. The creep deformation is observed to occur during nanoindentation of polymers. Procedures to minimize the creep effect are propose.
