Abstract: Disclosed herein are a supercontractible thin film comprising crystalline inclusion complex domains formed from poly(pseudo)rotaxanes or polyrotaxanes, and oriented polyethylene oxide domains physically crosslinked to the crystalline inclusion complex domains, wherein the poly(pseudo)rotaxanes or polyrotaxanes are formed from α-cyclodextrin and a polyethylene glycol having a number average molecular weight of from 500 to 10,000 Daltons, the polyethylene oxide has a number average molecular weight of from 200,000 to 10,000,000 Daltons, and the supercontractible thin film contracts by more than 50% of its original length upon wetting with water, a shape-adaptive supercontractile electrode and a shape-adaptive supercontractile electronic device. Also disclosed herein are methods of forming a supercontractible thin film, a freestanding film, and an electrode composite material.
