Abstract
The present invention, in some embodiments thereof, relates to material science in general, and, more particularly, to sequence variants of Stable Protein 1 (SP1), to uses thereof, for binding of carbon nanotubes, production of composite polymers and polymer materials, such as fabrics, based on SP1-polypeptide-carbon nanotube-complexes, and the use thereof for enhancing conductivity in tire.
Claims21
A composition of matter comprising carbon nanotubes non-covalently bound to chimeric stable protein 1 (SP1) polypeptide dispersed within a polymer resin, wherein said chimeric SP1 polypeptide:
- i) has at least 85% amino acid sequence identity to SEQ ID NO:4;
- ii) forms stable dimers;
- and
- iii) has a carbon nanotube binding peptide at the N-terminus of said SP1 polypeptide,
- wherein said carbon nanotubes are nanoscale hollow cylinders of graphite carbon atoms.
A composition of matter comprising carbon nanotubes non-covalently bound to chimeric stable protein 1 (SP1) polypeptide dispersed within a polymer resin, wherein said chimeric SP1 polypeptide comprises an SP1 polypeptide and a carbon nanotube binding peptide and wherein:
- i) said SP1 polypeptide has at least 90% amino acid sequence identity to SEQ ID NO:4;
- ii) said chimeric SP1 polypeptide forms stable dimers;
- and
- iii) said chimeric SP1 polypeptide has a carbon nanotube binding peptide at the N-terminus,
- wherein said carbon nanotubes are nanoscale hollow cylinders of graphite carbon atoms.
