Abstract

In the present work, a facile method is presented for fabrication of moisture sensitive porous polyurethane (PU) membranes with on-off function. A kind of supramolecular hydrogel precursor, never used as pore filling agent before, was firstly formed by the inclusion complexation of PEG diacrylate (PEGDA) with ?-cyclodextrin (?-CD) and subsequently in-situ UV photo-cross-linked in pores of the PU membranes. The moisture sensitive property of the supramolecular hydrogels was related to the amount of ?-CD added as well as the environmental relative humidity. Especially, the controlled on-off function of the hydrogel-containing porous PU membrane was confirmed from the results of microscopic observation. © 2011 Elsevier B.V. All rights reserved.
