The results demonstrated that the SF could show β-sheet conformation when the SF content in blend membranes was 10% (w/w) and 60–80% (w/w), while the pure SF membrane showed random coil conformation. A mechanism of the conformation transition was suggested in that the SF chain could use the rigid CS chain as a mold plate to stretch itself to form a β-sheet structure according to the strong hydrogen bond between CS and SF. Therefore, a new concept, named “Polymer-Induced Conformation Transition,” was proposed. © 1997 John Wiley & Sons, Inc. J Polym Sci B: Polym Phys 35: 2293–2296, 1997 References and Notes 1 J.
