A polyrotaxane gel having a polyethylene glycol (PEG) chain with large molecular weight and sparsely populated with α-cyclodextrins was synthesized. In this gel, the polymer chains with bulky end groups are neither covalently cross-linked like chemical gels nor do they interact like physical gels. The nanoscale heterogeneity in the structure and stress can be automatically equalized in the gel.
