Acid-Base Properties of the Components of Polymer Composite Materials

The set of substances that are used or may be used as polymer fillers is quite large. It comprises synthetic or natural inorganic and organic compounds, such as powdered, fibrillar or fabric ones. First of all, powdered fillers, being finely or coarsely dispersed, may be divided into two groups: inorganic compounds, such as oxides, metals, carbonates, phosphates, sulphates, talc, clays, mica, blacks, graphite, perlite, etc., and organic compounds — polystyrene, rubber, wood particles, etc. Secondly, a rich variety of fibrillar fillers are employed- inorganic fibers, such as glass, carbon and basalt fibers, and organic fibers — polyamide, aramid and viscose fibers. Finally, glass and textile fabrics are used as fillers.
