Abstract

Thioctic acid (TA) has been widely used to construct soft materials <i>via</i> supramolecular copolymerization with organic chemicals. In this study, TA and the inorganic compound MoS<sub>2</sub> are used to fabricate poly[TA-MoS2] <i>via</i> dynamic covalent and supramolecular interactions. Poly[TA-MoS2] exhibits good and long-lasting adhesion performance on various artificial surfaces, with an adhesion strength up to 3.72 MPa (15 days). Further, it exhibits tough adhesion effects in an aqueous environment. Moreover, poly[TA-MoS2] displays good thermal processing behavior, thus enabling its molding through 3D printing.
