Methods and systems of graft polymerization on a functionalized substrate
View Patent ↗Graft polymerization is fulfilled on a functionalized substrate. The functionalized substrate is prepared from a disulfide bond-containing feedstock and has been prepared for polymerization through the introduction of one or more polyfunctional monomers containing a disulfide bond breaking material functional group.
1. A grafted substrate comprising:
a substrate;
a polyfunctional monomer; and
a graft polymer grafted on the substrate via the polyfunctional monomer,
wherein the polyfunctional monomer is chemically bonded to the substrate and the polymer,
wherein the graft polymer is formed using a condensation polymerization reaction, and
wherein the polyfunctional monomer is bonded to the substrate via a disulfide bond.
2. The grafted substrate of claim 1 , wherein the polyfunctional monomer is bonded to the polymer via a sulfur-carbon bond.
3. The grafted substrate of claim 1 , wherein the substrate includes cysteine or cysteine-containing material.
4. The grafted substrate of claim 1 , wherein the polyfunctional monomer includes a functional group, the functional group includes at least one of an acid anhydride, an isothiocyanate, an acyl halide, an alcohol, an aldehyde, an alkene, an alkyne, an amine, a carboxylic acid, an ester and/or a thiol.
5. The grafted substrate of claim 1 , wherein the polyfunctional monomer includes a functional group, the functional group includes at least one ring, the ring being adapted to be opened to form at least a second functional group.
6. The grafted substrate of claim 1 , further comprising a polyester polymer,
wherein the polyester polymer is bonded to the polyfunctional monomer via an ester bond.
7. A functionalized substrate and graft polymer combination comprising:
a substrate; and
a polyfunctional monomer,
wherein the polyfunctional monomer including at least one first functional group and at least one second functional group, the first functional group including a first thiol group, and the second functional group including a second thiol group configured to react with a condensation polymerizable monomer, the first thiol group forming a disulfide bond with the substrate,
wherein the graft polymer is formed using a condensation polymerization reaction.
8. The functionalized substrate and graft polymer combination of claim 7 , wherein the polyfunctional group includes a third functional group, the third functional group includes at least one of an acid anhydride, an acyl halide, an isothiocyanate, an alcohol, an aldehyde, an alkene, an alkyne, an amine, a carboxylic acid, an ester and/or a thiol.
9. The functional substrate of claim 7 , wherein the polyfunctional group includes a third functional group, the third functional group includes at least one ring, the ring being adapted to be opened to form at least a fourth functional group.
