Abstract

This letter reports temperature-dependent recovery of atomic force microscope tip-formed indentations in a thermoset shape memory polymer. The indentations are made at both room temperature and 69 °C, and then recovered at temperatures between 40 °C and 70 °C. The shape recovery is more complete for higher anneal temperatures, and is relatively independent of time for 102 - 104 s. The experiments show shape memory in the 1-100 nm size scale.
