MASTERBATCHES FOR PREPARING A COMPOSITE MATERIAL BASED ON SEMI CRYSTALLINE POLYMER WITH ENHANCED CONDUCTIVITY PROPERTIES PROCESS AND COMPOSITE MATERIALS PRODUCED THEREFROM

摘要

The present invention relates to a masterbatch for use in a process of preparing a composite material comprising a blend of a first semi crystalline polymer with at least 5 wt% carbon nanotubes. Good dispersion of the carbon nanotube is obtained within the masterbatch and evidenced by the blending of the masterbatch with a second semi crystalline polymer miscible with the first one in respective proportions to obtain a composite material containing about 1 wt% of carbon nanotubes wherein said composite material yields an agglomerate area fraction U% lower than 2 and a surface resistivity lower than 10ohm/sq.
