Claims24
A method of coating a polypropylene (PP) material with a recombinant spider silk polypeptide which comprises the steps of:
- i) providing a solution which comprises at least one recombinant spider silk polypeptide comprising at least two identical repetitive units and a solvent, and
- ii) applying the solution on the polypropylene (PP) material and thereby coating the polypropylene (PP) material with the recombinant spider silk polypeptide.
A method of coating a synthetic inert or naturally occurring material with a recombinant silk polypeptide which comprises the steps of:
- i) providing a solution which comprises at least one recombinant silk polypeptide comprising at least two identical repetitive units and a solvent, and
- ii) applying the solution on the synthetic inert material or on the naturally occurring material and thereby coating the synthetic inert material or the natural occurring material with the recombinant silk polypeptide,
- wherein the recombinant silk polypeptide is non-covalently linked via at least one of an ionic linkage and a hydrophobic linkage to the synthetic inert material or naturally occurring material, and
- wherein the synthetic inert material is selected from the group consisting of polypropylene (PP) and polytetrafluorethylene (PTFE), or
- wherein the naturally occurring material is selected from the group consisting of skin and hair.
A method of coating a polypropylene (PP) material with a recombinant spider silk polypeptide, comprising the steps of:
- i) providing a solution essentially consisting of at least one recombinant spider silk polypeptide comprising at least two identical repetitive units and a solvent, and
- ii) applying the solution on the polypropylene material and thereby coating the polypropylene material with the recombinant spider silk polypeptide.
A polypropylene (PP) material coated with a recombinant spider silk polypeptide.
