    Effect of Strontium Titanate Nano Powder Addition on Some Mechanical Properties of Room Temperature Vulcanized Maxillofacial Silicone
    Author(s): Ali Saad Ahmed* and Mohammed Moudhaffer Mohammed Ali

    Introduction: Although both patients and prosthodontists accept silicone elastomers, additional improvements in their characteristics are needed to increase their performance. During the last decade, chemical researches had been conducted to produce a new generation of polymer with Nano filler integrated into the polymer matrix, resulting in a better material that combines the strength of the Nano filler with the flexibility of the organic polymer Aims: The study aims to evaluate the effects of strontium Titanate (SrTiO3) nano particles addition on some mechanical properties, including tensile strength, elongation percentage, tear strength, shore A hardness, and surface roughness, of VST-50 maxillofacial silicone elastomer. Materials and Method: SrTiO3 nanoparticles (average particle size 80-100nm) were int.. Read More»
