Materials. Unless otherwise stated, all chemicals and solvents were analytical grade materials (Fluka and B.D.H.), and were used as received. The water used for washing and preparation of aqueous electrolyte solutions was deionized and freshly double-distilled in a fused-silica still. All liquids are filtered (0.22 pm Millipore or Fluoropore filters) prior to introduction into the glass cell. The mica used throughout was Best Quality FS/GS grade 2 Muscovite Ruby mica, mined in Kenya (Mica and Micanite Ltd., U.K.). 

Carbon black at various loadings, as well as in combination with mica, and mica and flake graphite, was used. The range of loadings used is shown in Table II. The graphite used was Cummings Moore 6894 graphite, while the mica used was Micro-Mica CIOOO. This has a platy particle shape, with particle size of 10 to 20 microns in diameter and a theoretical mesh size of 1000. 

Roscoelite is a vanadium-containing form of mica used to make vanadium metal. Although the fraction of vanadium in the ore is variable, roscoelite can be described as K2V4Al2Si602o(OH)4. Another way to describe the vanadium content of this mineral is to say that it has the equivalent of up to 28% V2O3. 

Muscovite is the principal mica used because of its abundance and superior electrical properties. Phlogopite...

Similar studies have been carried out on the adhesion of PDMS to polycarbonate using thermal gradients and x-ray photoelectron spectroscopy, to mica using atomic force microscopy, and to glass - or to silicon using measurements of force, contact angle, or other properties. There has also been considerable interest in the adhesion strength between coated particles and polymer matrixes. Surface functionalization has been used to improve adhesion. - ... 

A study of the effects of 11 surface-treating agents and three modified polypropylene resins on the strength properties of mica-reinforced polypropylene was presented in a paper at the 1990 annual SPI conference (28). HAR-160 mica, the mica used in the previous section on annealing, was also used in this study. The polypropylene used in the study was Profax 6523 pm, which has a nominal melt index of 4. Surface treatments and treatment levels are listed in Table 14.29.
