Conductive polymer foams, method of manufacture, and uses thereof

Abstract

A method of manufacturing a polymer foam composite is described, the method comprising forming an article having a first surface and an opposite second surface from a precursor composition, the precursor composition comprising a polymer foam precursor composition, and a filler composition comprising a plurality of magnetic, electrically conductive particles; foaming the precursor composition to form a plurality of cells in precursor composition; applying a magnetic field to the foamed precursor composition, wherein the magnetic field is of a strength and applied for a time effective to align the electrically conductive, magnetic particles into mutually isolated chains between the first surface and the opposite second surface of the article; and solidifying the polymer foam precursor composition to provide a polymer foam composite having a density of about 1 to about 125 pounds per cubic foot and a volume resistivity of about 10-3 ohm-cm to about 103 ohm-cm at a pressure of 60 pounds per square inch. Polymer foam composites made by this method are also described, as well as articles formed therefrom.
描述了一种制造聚合物泡沫复合材料的方法,所述方法包括:由前体组合物形成具有第一表面和相反的第二表面的制品,所述前体组合物包含聚合物泡沫前体组合物、和含有多个磁性导电颗粒的填料组合物;使所述前体组合物发泡以在所述前体组合物中形成多个孔;向所述发泡的前体组合物施加磁场,其中所述磁场的强度和施加时间有效地使所述磁性导电颗粒在所述制品的第一表面和相反的第二表面之间排列成相互隔开的链;和使所述聚合物泡沫前体组合物固化,以提供密度为约1至约125磅/立方英尺和在60磅每平方英寸的压力下体积电阻率为约10<sup>-3</sup>欧姆-cm至约10<sup>3</sup>欧姆-cm的聚合物泡沫复合材料。还描述了通过该方法制备的聚合物泡沫复合材料,以及由其形成的制品。
