摘要： Reversibly crosslinkable compositions are provided for forming removable crosslinked films. A reversibly crosslinkable composition may comprise entangled chains of a polysiloxane comprising pendant functional groups having formula —NH—(C═O)—X—COOH, wherein X is an alkyl group, an alkenyl group, or an aryl group; a plurality of inorganic oxide nanoparticles; and a solvent; wherein non-covalent bonds between the pendant functional groups and the inorganic oxide nanoparticles crosslink the entangled chains to form a polymeric matrix in the absence of the solvent, wherein the non-covalent bonds dissociate and the polymeric matrix collapses in the presence of water and heat.
