First claim
Opening claim text (preview).
1 .- 20 . (canceled) 21 . A process of forming a cross-linked polydimethylsiloxane (PDMS) material, the process comprising utilizing hexane-1,3,4-triol as a bio-derived cross-linker to form the cross-linked PDMS material. 22 . The process of claim 21 , further comprising forming the hexane-1,3,4-triol from biorenewable cis-3-hexenol. 23 . The process of claim 21 , wherein the cross-linked PDMS material is formed via a chemical reaction of a hydride-functionalized PDMS material and hexane-1,3,4-triol. 24 . The process of claim 21 , wherein the cross-linked PDMS material is formed via a chemical reaction of an alkoxy-functionalized PDMS material and hexane-1,3,4-triol. 25 . The process of claim 24 , wherein the alkoxy-functionalized PDMS material includes a methoxy-functionalized PDMS material. 26 . A process of forming a cross-linked polydimethylsiloxane (PDMS) material, the process comprising utilizing a hexane-1,3,4-triol derivative as a bio-derived cross-linker to form the cross-linked PDMS material. 27 . The process of claim 26 , further comprising: forming hexane-1,3,4-triol from biorenewable cis-3-hexenol; and forming the hexane-1,3,4-triol derivative from the hexane-1,3,4-triol. 28 . The process of claim 26 , wherein the hexane-1,3,4-triol derivative includes multiple acrylate groups. 29 . The process of claim 26 , wherein the hexane-1,3,4-triol derivative includes multiple vinyl groups. 30 . The process of claim 26 , wherein the hexane-1,3,4-triol derivative includes multiple acetate groups. 31 . The process of claim 26 , wherein the hexane-1,3,4-triol derivative includes multiple thiol groups. 32 . The process of claim 26 , wherein utilizing the hexane-1,3,4-triol derivative as the bio-derived cross-linker to form the cross-linked PDMS material includes chemically reacting the hexane-1,3,4-triol derivative with a functionalized PDMS material. 33 . The process of claim 32 , wherein the hexane-1,3,4-triol derivative includes multiple acrylate groups, and wherein the functionalized PDMS material includes a hydride-functionalized PDMS material. 34 . The process of claim 32 , wherein the hexane-1,3,4-triol derivative includes multiple vinyl groups, and wherein the functionalized PDMS material includes a vinyl-functionalized PDMS material. 35 . The process of claim 32 , wherein the hexane-1,3,4-triol derivative includes multiple acetate groups, and wherein the functionalized PDMS material includes a hydoxy-functionalized PDMS material. 36 . The process of claim 32 , wherein the hexane-1,3,4-triol derivative includes multiple thiol groups, and wherein the functionalized PDMS material includes a vinyl-functionalized PDMS material. 37 . The process of claim 36 , wherein the hexane-1,3,4-triol derivative that includes multiple thiol groups has the following chemical structure: 38 . A process of forming a cross-linked polymeric material, the process comprising: utilizing biorenewable cis-3-hexenol to form a bio-derived cross-linker that includes multiple thiol groups; and utilizing the bio-derived cross-linker to form a cross-linked polymeric material that includes a polymeric network of disulfide linkages. 39 . The process of claim 38 , wherein the bio-derived cross-linker that includes multiple thiol groups has the following chemical structure: 40 . The process of claim 38 , wherein the bio-derived cross-linker that includes multiple thiol groups undergoes an oxidation-reduction reaction to form the polymeric network of disulfide linkages.
