    • A flame retardant filler having brominated silica particles, for example, imparts flame retardancy to manufactured articles such as printed circuit boards (PCBs), connectors, and other articles of manufacture that employ thermosetting plastics or thermoplastics. In this example, brominated silica particles serve both as a filler for rheology control (viscosity, flow, etc.) and a flame retardant. In an exemplary application, a PCB laminate stack-up includes conductive planes separated from each other by a dielectric material that includes a flame retardant filler comprised of brominated silica particles. In an exemplary method of synthesizing the brominated silica particles, a monomer having a brominated aromatic functional group is reacted with functionalized silica particles (e.g., isocyanate, vinyl, amine, or epoxy functionalized silica particles). Alternatively, a monomer having a brominated aromatic functional group may be reacted with a silane to produce a brominated alkoxysilane monomer, which is then reacted with the surface of silica particles.
    • 具有溴化二氧化硅颗粒的阻燃填料例如赋予制造品例如印刷电路板(PCB),连接器以及使用热塑性塑料或热塑性塑料的其它制品的阻燃性。 在该实施例中,溴化二氧化硅颗粒既用作流变控制(粘度,流动等)和阻燃剂的填料。 在示例性应用中,PCB叠层叠层包括通过包含由溴化二氧化硅颗粒构成的阻燃填料的介电材料彼此分离的导电平面。 在合成溴化二氧化硅颗粒的示例性方法中,具有溴化芳族官能团的单体与官能化二氧化硅颗粒(例如异氰酸酯,乙烯基,胺或环氧官能化二氧化硅颗粒)反应。 或者,具有溴化芳族官能团的单体可以与硅烷反应生成溴化烷氧基硅烷单体,然后与二氧化硅颗粒的表面反应。
