Solid state methods such as high energy ball milling (HEBM) have been successfully used to prepare polymer nanocomposites, reaching uniform dispersion of the particles even for relatively high loadings [140,141,142,143].
Interestingly, for ball milling at 400 rpm, the peak was disappeared after 2 h of milling (C 400-2), whereas, the reflection was still present even after 4 h of milling at 200 rpm (C 200-4). As described in the experimental section, milling of nanoclay was thus continued up to 4 h and 2 h for 200 rpm and 400 rpm, respectively.
The resulting organoclay suspension was mixed further for 12 h. All products were washed until free from bromide anions and dried at 90oC. Finally, the …

China clay was grinded (dry grinding) in a planetary ball mill (Model PM 100) to reduce the particle size to the nano range. The size of the china clay varied from a minimum of about 0.5 micron to a maximum of 74 microns. The average diameter for the individual clays varied from 1.5 to 38 microns. Then the size of the clay reduced to nano level.
