Typical plastic materials have a low electrical conductivity and dust adhesion to a product surface due mainly to static causes various disadvantages.As a countermeasure against static of plastic materials, the use of antistatic agents is gathering attention from viewpoints of convenience and costs, and the effect of surfactant agent to lower surface resistance have been reported. But, surfactant-agents tend to unlimitedly bleed out from plastic base materials. Therefore, it is difficult to keep antistatic property. Donor-accepter molecular compound antistatic agent (BN105) has unique properties that are capable of stably dispersing and remaining in a resin matrix and capable of instantly leaking static not only on a product surface but also through the inside. A little addition of BN105 may allow the prevention of static buildup efficiently without losing the other bulk properties of the matrix polymer resin. In the present study, cyclo olefin polymer (COP) / BN105 composite materials were prepared by using injection molding. Surface resistance of the molded product decreased to 2 �~ 10^11 ƒ¶ /sq along with an increase in BN105 content range up to 2 wt%, and these samples showed excellent dust resistance. In addition, the samples containing BN105 less than 5 wt% hardly had a transmittance decrease. Thus, the results offered hope for the creation of a composite material maintaining the high transparency of the base resin COP.
