masterbatches for the preparation of composite materials with enhanced conductivity properties, process and composite materials produced

摘要

The present invention relates to a masterbatch for use in a process for the preparation of a composite material, the standard mixture comprising a mixture of a first amorphous polymer with carbon nanotubes, and at least 5% by weight. carbon nanotube weight based on the total weight of the standard mixture, preferably from 5% to 15%, where the standard mixture exhibits a high melt flow rate hlmi1 of less than 40 g / 10 min determined at 200 ° C under a load of 21.6 kg according to iso 1133 and the first amorphous polymer has a melt flow index mfi1 of at least 10 g / 10 min determined at 200 ° c under a load of 5 kg according to iso 1133h. The invention also relates to the process for preparing such a standard mixture and to the process of preparing a composite material utilizing said standard mixture.
