Silica fillers are well known to improve the mechanical properties of elastomers.Nevertheless, the silica filler particles tend to aggregate and affect the properties of the elastomer. In the present study, the silica filler was modified by silane coupling agent (A-151) in order to improve the dispersion of the filler in silicone rubber. The composites samples added with surface treated silica filler was characterized by FT-IR, bound rubber, and fluorescent microscope with that reinforced by the unmodified filler as a comparison. FT-IR results evidences the successful surface modified by silan...
