pH-Switchable supramolecular “sliding” gels based on polyrotaxanes of polyethyleneimine-block-poly(ethylene oxide)-block-polyethyleneimine block copolymer and α-cyclodextrin: synthesis and swelling behaviour
Abstract
A new type of pH-switchable supramolecular sliding gel has been synthesized, based on polyrotaxanes of polyethyleneimine-block-poly(ethylene oxide)-block-polyethyleneimine
