ANOMALY IN STRETCHING-DRIVEN SWELLING OF SLIDE-RING GELS WITH MOVABLE CROSS-LINKS
Introduction Slide-ring (SR) gels have attracted considerable interest as a novel type of polymer gel whose cross-links are movable along the network strands, in contrast to the topologically fixed cross-links of classical gels. The network strands in SR gels are topologically interlocked by figure-ofeight cross-links (slide-rings). The movable crosslinks are expected to have a function of pulleys when the gels deform. These cross-links slide along the network strands so that the configurational entropy of the networks can be maximized, i.e., the resultant entropic force can be minimized. This pulley effect is a property unparalleled in polymer gels. Okumura and Ito1 first synthesized polyrotaxane (PR)based SR gels by the intermolecular cross-linking of α-cyclodextrin (α-CD) contained in polyethylene glycol (PEG).
