Abstract:
1. A thermally reversible composite material, comprising: a Polyhedral Oligomeric Silsesquioxane (POSS), comprising a plurality of dienophile groups; and a cross-linking agent, comprising at least two conjugated diene groups, wherein the cross-linking agent reacts with the plurality of dienophile groups of the POSS through the conjugated diene groups to carry out a thermally reversible Diels-Alder cycloaddition cross-linking reaction, wherein the plurality of dienophile groups of the Polyhedral Oligomeric Silsesquioxane are identical or different, independently selected from the group consisting of the following or any combination thereof, where X is a nitrogen atom or an oxygen atom: and R l and R 2 are identical or different, independently selected from the group consisting of the following or any combination thereof: hydrogen atom, alkyl, aralkyl, oxyalkyl, and oxyaralkyl, wherein the number of the carbon atoms of R l or R 2 is one selected from one to twenty.
