    • The present invention provides for a polymer composite foam with a treated filler and methods for making the same. The polymer composite foam includes a polymer capable of being formed into a polymeric foam and a treated filler, wherein the polymer defines a plurality of cells dispersed therethrough and the treated filler is dispersed throughout the polymer. The filler is treated by techniques which exfoliate, delaminate or intercalate the filler particles into individual micro and/or nano size particulates and platelets. Ideally, the treated filler has a median particle size ranging from about 0.1 nm-10 μm. The treated filler enhances the rigidity, barrier properties, heat deflection temperature, nucleation characteristics, fire retardant characteristics and impact properties of the foam. The products fabricated from the polymer composite foam include containers, cups, sleeves, bags, plates, bowls, protective packaging, boards, sheets, void fillers, storageware, dinnerware and cookware. The present invention also provides for methods of fabricating the polymer composite foam.
    • 本发明提供一种具有处理填料的聚合物复合泡沫体及其制备方法。 聚合物复合泡沫体包括能够形成聚合物泡沫和经处理的填料的聚合物,其中聚合物限定了分散在其中的多个细胞,并且处理的填料分散在整个聚合物中。 填料通过将填料颗粒剥离,分层或嵌入到单独的微粒和/或纳米尺寸颗粒和血小板中的技术来处理。 理想地,处理过的填料的中值粒度为约0.1nm-10μm。 经处理的填料增强了泡沫的刚性,阻隔性能,热变形温度,成核特性,阻燃特性和冲击性能。 由聚合物复合泡沫制成的产品包括容器,杯子,袖子,袋子,盘子,碗,保护性包装,板,片,空隙填料,储存器皿,餐具和炊具。 本发明还提供了制造聚合物复合泡沫体的方法。
