Abstract
γ-Radiation was utilized to graft acrylic acid in the vapor phase to the surface of glass fibers and quartz particles. This treatment improved the wettability of the filler with the polymeric matrix and enhanced the mechanical properties of the composite. Samples were prepared from the unfilled dental resin, and from composites containing untreated, silane treated and polyacrylic acid-grafted fillers. These composites contained 30, 45 and 69 vol.% filler in each category. The composites containing grafted filler were superior in hardness and compressive strength, and equivalent in abrasion resistance to those with silane treated fillers. However, both treatments showed at least a 50% improvement in compressive strength and a 300% reduction in wear over composites with untreated filler. This improvement was even more substantial when glass fibers were used as the filler material.
