A method for producing a carbon nanotube-metal composite in which carbon nanotubes are layered on a metal substrate, the method comprising: (i) depositing a liquid, in which carbon nanotubes are suspended, onto said metal substrate; (ii) during or after step (i), subjecting said liquid to a shearing force sufficient to spatially confine the liquid to induce at least partial alignment of said carbon nanotubes on said metal substrate; and (iii) removing said liquid to produce said carbon nanotube-metal composite; wherein, after step (iii), the lengthwise dimensions of said carbon nanotubes are adhered to and oriented parallel with said metal surface, and said carbon nanotubes are at least partially aligned with each other. In some embodiments, the liquid is deposited in the form of droplets, and the droplets are subjected to a shearing force to cause them to elongate, which induces at least partial alignment of the carbon nanotubes.

Metal-carbon composites and methods for their production

A silane-modified polyester blend comprising a polyester polymer homogeneously blended with silane molecules containing two or three alkoxy groups bound to the silicon atom, wherein said silane molecules are present in said polyester blend in an amount of 0.05-20 wt % (or, e.g., 0.05-10 wt %, 0.05-5 wt %, or 0.05-2 wt %). The polyester polymer may, in particular embodiments, be a polyhydroxyalkanoate, terephthalate-based polyester, adipate-based, or succinate-based polyester. The silane molecule may be according to the formula (RO)SiRR, wherein Rgroups are independently selected from alkyl groups containing 1-4 carbon atoms; and Rand Rare independently selected from ORgroups and alkyl groups containing 1-12 carbon atoms, provided that at least one of Rand Ris an alkyl group, wherein the alkyl group optionally includes one or more heteroatoms selected from oxygen, nitrogen, halogen, sulfur, phosphorus, and silicon. Methods for producing the silane-modified polyester blend are also described.
