Abstract
Two different methods for the preparation of graphite fluoride-modified powders were studied in a dry treating system. Nylon 12, polyethylene, and epoxy resin microspheres were used as core materials.
Using the binary powders blending method (called the powder/powder system blending method) it was impossible to prepare the regular monoparticle layer of graphite fluoride on each core particle.
On the other hand, with another method utilizing a strong impact force (the high speed impact treatment method) it was possible to easily prepare the fine arrangement of graphite fluoride particles on each core particle. From the results observed on the powder dispersability in water and SEM observation, it is found that fine graphite fluoride particles are homogeneously fixed onto the surface of each core particle. This tendency did not depend on the triboelectronic series of the materials.
