An electrically conductive yarn or film and method of manufacturing thereof in which a SP1/nanoparticle complex bound to the yarn or film serves as a platform for adhesion of a metallic coating.

Conductive yarn

The present invention, relates to composition of matter comprising sequence variants of Stable Protein 1 (SP1) and carbon nanotubes or carbon black, and optionally comprising latex. This invention also relates to surfaces (e.g. metal wires, cords, and polymeric and non polymeric fibers, yarns, films or fabrics, wood and nano, micro and macro particles) comprising this composition of matter, to methods for producing them, and to uses thereof in the preparation and formation of improved composite materials, including rubber, and rubber compound composites.

Composition comprising SP1 and carbon based nanoparticles and uses thereof

Use of homogeneous catalytic systems which include as a pre-catalyst a complex of a group 4 metal and a Salan ligand in the polymerization of alpha-olefins, is disclosed. The Salan ligand is characterized by a sequential diamino-containing skeleton unit which is non-symmetric, and the pre-catalysts can also be such that are devoid of a symmetry element. The disclosed polymerization results in alpha-olefin polymers such as polypropylene which are characterized by high levels of tacticity. Also disclosed are novel Salan ligands and novel complexes thereof with group 4 metals.
