Local and network structure of thermoreversible polyrotaxane hydrogels based on poly(ethylene glycol) and methylated [alpha]-cyclodextrins
Article Abstract:
Differential scanning microcalorimetry, rheometry and X-ray diffractometry (XRD) are used to investigate the thermoreversible gelation and microphase formation of aqueous solution of a methylated polyrotaxane (MePR). The XRD studies revealed that the network structure in the solution is formed by crystal-like junctions consisting of well-defined aggregates of methylated cyclodextrins which are arranged along the poly-(ethylene glycol) chain.
