摘要
Polyrotaxanes(PRs)constructed by macrocycle-threading polymers has been broadly developed for soft materials due to its unique supramolecular topological architecture,which can greatly improve the mechanical nature of materials[1,2].Based on this,Choi and co-workers incorporatedα-cyclodextrin(α-CD)based PR into a traditional polyacrylic acid adhesive,giving the polymer network unprecedented elasticity derived from the slip ring motion of the PR.This binder combination allows the pulverized silicon particles to remain agglomerated without disintegrating,allowing silicon particulate anodes to have stable cycle life at commercial levels of areal capacity[3].Ito and co-workers exploited an optically transparent elastomer bearing high toughness and excellent extensibility utilizing a PR composed ofα-CD and polyethylene glycol(PEG)as a cross-linking agent.
