An organic/inorganic hybrid soft material for supramolecular adhesion

Abstract

Thioctic acid (TA) has been widely used to construct soft materials by supramolecular copolymerizing with organic chemicals. In this study, TA and inorganic compound MoS2 are applied to fabricate poly[TA-MoS2] via dynamic covalent and supramolecular interaction. Poly[TA-MoS2] exhibits good and long-lasting adhesion performances on various artificial surfaces, with the adhesion strength up to 3.72 MPa. Tough adhesion effects of poly[TA-MoS2] are obtained in the presence of the aqueous environment. Moreover, poly[TA-MoS2] displays good thermal processing behavior, enabling its molding through 3D printing.
