摘要： Ethyl cellulose (EC) membranes can be combined with efficient plasticizers derived from renewable resources to form supramolecular systems. In this paper, a novel ricinoleic acid-based sulfhydryl triol (STRA) was first synthesized and used as a plasticizer for EC membranes. A supramolecular membrane of EC and STRA using van der Waals forces was designed. The morphology, hydrophilic performance, thermal stability, and mechanical properties of the composites were investigated. While pure EC is brittle, its membrane ductility and hydrophilic performance can be improved by integration with STRA. The highest tensile strength was found in EC/STRA (90/10) (8.37 MPa). Impressively, the EC/STRA( 60/40) and EC/STRA(50/50) elongation at break values were 17.4 and 20.2 times higher, respectively, than that of pure EC. This novel ricinoleic acid-based sulfhydryl triol can be used as a feedstock for hydrophobic EC membranes. (C) 2017 Published by Elsevier Ltd.
