Shape recovery of nanoscale imprints in a thermoset “shape memory” polymer
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 hi...

| Zusammenfassung: | 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 102–104s. The experiments show shape memory in the 1–100nm size scale. |
