    • The disclosed is a colored polymer composition which includes carbon fibrous structures and a coloring agent in a polymer matrix, wherein the carbon fibrous structure comprises a three dimensional network of carbon fibers each having an outside diameter of 15-100 nm, wherein the carbon fibrous structure further comprises a granular part with which the carbon fibers are tied together in the state that the concerned carbon fibers are externally elongated therefrom, and wherein the granular part is produced in a growth process of the carbon fibers. It is the colored polymer composition which includes novel carbon fibrous structures having preferable physical properties as a filler for composite material, and of being able to improve electrical, mechanical and thermal properties of a matrix while maintaining other properties of the matrix, in a small adding amount, and which can show a color as pleases. When a white coloring agent is used as the coloring agent, the darkness in color tone of the polymer which is due to the addition of the carbon fibrous structure can be easily corrected by adding a relatively small amount of the white coloring agent as the coloring agent.
    • 所公开的是在聚合物基体中包含碳纤维结构和着色剂的着色聚合物组合物,其中碳纤维结构包括每个外径为15-100nm的碳纤维的三维网络,其中碳纤维结构 进一步包括在所述碳纤维从外部延伸的状态下将碳纤维捆扎在一起的颗粒部分,并且其中所述颗粒部分在碳纤维的生长过程中产生。 作为复合材料的填充材料具有优选物性的新型碳纤维结构体,能够在保持基体的其他特性的同时,能够提高基体的电学,机械和热学特性的着色聚合物组合物 数量,并且可以显示出喜欢的颜色。 当使用白色着色剂作为着色剂时,通过添加相对少量的白色着色剂作为着色剂,可以容易地校正由于添加碳纤维结构而导致的聚合物色调的黑暗 。
