Self-healing organosiloxane materials containing reversible and energy-dispersive crosslinking domains

A crosslinked copolymeric material comprising first and second copolymers, said first copolymer comprising:

• at least one first silicon component attached to at least two first crosslinking components in the form of a block copolymer, a graft copolymer, or a combination thereof;
• wherein the first silicon component comprises a polymer selected from the group consisting of a silicate, a siloxane, a silsesquioxane, and a mixture of any two or more thereof;
• wherein the first crosslinking components are polymers and comprise at least two intermediate strength folding domains selected from the group consisting of a first beta sheet-forming peptide, a first alpha helix-forming peptide, and a first modular molecular loop;
• said second copolymer comprising:
• at least one second silicon component attached to at least two second crosslinking components in the form of a block copolymer, a graft copolymer, or a mixture thereof;
• wherein the second silicon component comprises a polymer selected from the group consisting of a silicate, a siloxane, a silsesquioxane, and a mixture of any two or more thereof;
• wherein the second crosslinking components are polymers and comprise at least two intermediate strength folding domains selected from the group consisting of a second beta sheet-forming peptide, a second alpha helix-forming peptide, and a second modular molecular loop;
• wherein the second copolymer can be the same as or different than the first copolymer;
• wherein the first and second crosslinking components may be the same or different, and at least one of the first and second crosslinking components is the same molecule and is covalently attached to both the first and second silicon components,
• wherein the intermediate strength folding domains form a plurality of intermediate strength crosslinks within the material of at least about 10 piconewtons and less than about 1000 piconewtons in strength;
• wherein the crosslinked material exhibits at least about 5% self-healing upon disruption of its structure.
