    Abstract: This invention relates to coated polyurethane foams and to a process for preparing coated polyurethane foams. More specifically, these coated polyurethane foams comprise (a) a polyurethane foam substrate, and (b) at least one bilayer of a coating composition on the foam substrate which comprises (1) a layer of a positively or negatively charged carbon allotrope, and (2) a layer of a positively or negatively charged polymer. When the carbon allotrope is positively charged, the other material is negatively charged, and vice versa. The final product (i.e. coated polyurethane foam) contains at least 1% by weight of the coating composition, based on 100% by weight of the coated polyurethane foam. The foams described herein have a surface resistivity of less than or equal to 1012 ohms per square.

    Abstract translation: 本发明涉及涂覆的聚氨酯泡沫以及制备涂覆的聚氨酯泡沫的方法。 更具体地说,这些涂覆的聚氨酯泡沫包括(a)聚氨酯泡沫基材,和(b)在泡沫基材上的至少一层涂料组合物,其包含(1)带正电荷或带负电荷的碳同素异形体层和( 2)一个带正电荷或带负电荷的聚合物层。 当碳同素异形体带正电时,其他材料带负电,反之亦然。 基于100重量%的涂覆的聚氨酯泡沫,最终产品(即涂布的聚氨酯泡沫)含有至少1重量%的涂料组合物。 本文所述的泡沫具有小于或等于1012欧姆/平方的表面电阻率。
