"Polyrotaxane-interlocked" gels which exhibit periodic swelling/deswelling oscillations without "on/off" switching of external stimuli are presented. The mechanical oscillation is driven by the redox oscillation in the BZ reaction and enhanced by the unique topological structure.
本工作利用“聚輪烷互鎖結(jié)構(gòu)”作為交聯(lián)點(diǎn)，構(gòu)筑了新型結(jié)構(gòu)自振蕩高分子凝膠。這種新交聯(lián)結(jié)構(gòu)的引入可以提高凝膠對(duì)外界因素的響應(yīng)速率和響應(yīng)幅度，為新型自振蕩凝膠驅(qū)動(dòng)器性能的改善提供幫助。
