摘要

Abstract

Supramolecular adhesives that enable debonding on-demand are of significant research interest for the development of adaptive and smart materials

yet

biodegrable supramolecular adhesives have been rarely exploited. Herein

telechelic

three-armed and four-armed CO

-based polyols with close molecular weights and various CO

content (or carbonate unite content) have been synthesized

via

a zinc-cobalt double metal cyanide complex catalyzed ring-opening copolymerization of CO

and propylene oxide

and further exploited as sustainable and biodegradable building blocks for supramolecular polymers (SMPs) with 2-ureido-4[1

]-pyrimidinone (UPy) motifs. Notably

the orthogonal modulation of the CO

content and the topology of CO

-based polyols provide a unique opportunity to fine-tune the surface energy as well as the cohesive strength of the resulting CO

-based SMPs. Notably

a three-armed SMP with 44% CO

(3UPy-CO

-44%) can well balance the trade-off between surface energy and cohesive strength

therefore bestowing a high adhesive strength of 7.5 and 9.7 MPa towards stainless steel and wood substrates respectively by testing the corresponding single lap joints. Moreover

the light-responsive adhesion property of 3UPy-CO

-44% has been demonstrated exemplarily by blending with a UV sensitizer.
