    Abstract: The present invention relates to the development of electrostatic dissipative (ESD) electronic packaging materials based on the electrically conducting nanofiller decorated polyurethane foams and also describes a process for the preparation of the same. More specifically it relates to the development of electrically conducting foams by providing a coating of 0.003 to 2.97 vol % loading of electrically conducting materials (like conducting polymers, functionalized carbon nanotubes, graphene analogues etc) over/onto otherwise electrically insulating surface of foams. The combination of low density, mechanical flexibility, resilience and surface conductivity collectively contribute towards their excellent shock absorption and static charge dissipation capabilities. In particular, these foams display surface resistivity value

    Abstract translation: 本发明涉及基于导电纳米填料装饰的聚氨酯泡沫的静电消散（ESD）电子包装材料的开发，并且还描述了其制备方法。 更具体地说，它涉及通过在泡沫的另外的电绝缘表面上/之上提供0.003至2.97体积％的导电材料（如导电聚合物，官能化碳纳米管，石墨烯类似物等）负载的涂层来开发导电泡沫体。 低密度，机械灵活性，弹性和表面电导率的组合共同促成了它们优异的减震和静电荷消散能力。 特别地，这些泡沫显示表面电阻率值<109欧姆/平方英尺和静电荷耗散时间<0.5秒，这清楚地表明了其电子封装应用的潜力。 此外，这些泡沫也可用于抗静电除尘过滤器，洁净室/医疗服装，无静电鞋类，静电消耗性内饰物品，抗静电/消散地板/瓷砖等。

    Abstract: The present invention relates to a foam polystyrene-based bead. The foam polystyrene-based bead includes: a core containing a styrene-based resin, a char-generating thermoplastic resin, and an expanded inorganic material; and a skin disposed on the surface of the core, wherein the skin contains a resin of which the glass transition temperature is below around 120° C. The foam is contained in the core or skin. The core may further include a carbon filler. Foam produced from the expandable polystyrene beads is not an inherently self-extinguishing flame retardant material yet can have good non-flammability comparable to or better than that of inherently flame retardant materials (Non flammability level 3) as measured in accordance with KS F ISO 5660-1, heat insulation properties, and mechanical properties.
