Preparation and properties of the new antistatic fiber with carbon nanotubes

A new antistatic master batch with high efficacy and durability was obtained by dispersing multi-wall carbon nanotubes into the antistatic agent PR-86. One merit of the antistatic master batch was that good antistatic PP fiber with " fibril in matrix " structure can be prepared with just 0.5% (mass fraction) of it. The antistatic mechanism of the fiber is the polarization of " island " in the fiber under the action of electric field and discharging electric charge within the fiber. By using the multi-wall carbon nanotubes, the degree of the polarization of " island " is enhanced, which further strengthens the effect of the master batch's antistatic property. The fiber has a durable antistatic characteristic which is free from the influence of relative humidity. And the antistatic master batch has no influence on other properties of the fiber.
