Abstract: A reversibly adhesive film, comprising: at least two hydroxyl-bearing polymer chains being crosslinked by one or more boronic ester bonds, the film having accessible hydroxyl groups at a surface of the film. An reversible adhesive, comprising: a first film layer, the first film layer comprising at least two first hydroxyl-bearing polymer chains crosslinked by first crosslinks that comprise one or more boronic ester bonds; and a second film layer, the first second layer comprising at least two second hydroxyl-bearing polymer chains crosslinked by second crosslinks that comprise one or more boronic ester bonds, wherein (1) the first hydroxyl-bearing polymer chains differ from the second hydroxyl-bearing polymer chains in one or more of composition and concentration, or (2) the boronic ester bonds are present in the first film layer at a different density than the boronic ester bonds in the second film layer, or (3) both (1) and (2).
