An adhesive that includes a polymer network capable of conversion between two different elastic modulus states with essentially no residual stress evolved in conversion between the two different elastic modulus states, wherein the polymer network comprises either or both of (i) poly (2-hydroxy ethyl methacrylate) (PHEMA) hydrogel and/or a copolymers thereof, and (ii) a shape memory polymer. The technology also concerns methods of using such adhesives.

Intrinsically reversible superglues

Provided are highly water-resistant, flexible cementitious coating compositions comprising: an aqueous styrene-butadiene latex, one or more epoxy silane, cement, and one or more solid filler. The epoxy silane may comprise one or more epoxy functional groups and one or more hydrolysable functional groups selected from siloxy, silane, and, silanol or combinations thereof. Also provided are kits comprising the components of the cementitious coating compositions, methods for providing coatings, layers or membranes derived from such wet compositions, as well as the coatings, layers or membranes derived therefrom.
