Masterbatch for producing composite materials based on semi-crystalline polymers having improved electrical conductivity, method for producing the same, and composite materials produced therefrom

摘要

The present invention relates to a masterbatch for use in a method of making a composite material, comprising a blend of a first semi-crystalline polymer and at least 5 wt% carbon nanotubes. The carbon nanotubes are well dispersed in the masterbatch, and a second batch miscible with the masterbatch containing the first semi-crystalline polymer results in a composite material containing about 1% by weight of carbon nanotubes. can get. The aggregate area ratio U% of the composite material is 2 or less, and the surface resistivity is 10 5 ohm / square or less.
