Hardly Water-Soluble Pseudo-Polyrotaxane Nanosheets Comprising Polyethylene-Oxide-Modified Polydimethylsiloxane and Gamma-Cyclodextrin

Abstract We have successfully prepared hardy water-soluble pseudo-polyrotaxane nanosheets composed of carboxy group-terminated polyethylene oxide (PEO)-modified polydimethylsiloxane and γ-cyclodextrin (CD). These pseudo-polyrotaxane nanosheets are more water-insoluble than previously reported pseudo-polyrotaxane nanosheets composed of pluronic—a triblock polymer comprising PEO, polypropylene oxide (PPO), and PEO—and β-CD, and have potential applications as surface treatment agents.
