ABSTRACT: A series of PUEs which use β-CD as cross-linker were synthesized. Nanoindentation measurements
of mechanical properties of these PUEs were made. Load and depth sensing indentation and nano
DMA mode were used to evaluate mechanical properties of PUEs in nano-scale. The difference
between the results from two modes proved the microphase separation in PUEs and to investigate
PUE from hard domains and soft domains was of great significance.
