Superstrong Water-Based Supramolecular Adhesives Derived from Poly(vinyl alcohol)/Poly(acrylic acid) Complexes

It remains a great challenge for low-cost and mass fabrication of water-based adhesives with good adhesion performance. In this study, superstrong water-based supramolecular adhesives with long-term stability are fabricated by complexation of commercially available poly(vinyl alcohol) (PVA) and poly(acrylic acid) (PAA) in aqueous solution. The gel-like PVA/PAA adhesives can be conveniently injected and spread on targeted location for firm...
