    • A dispersant for a carbon nanotube and a composition comprising the same are provided, wherein the dispersant is comprised of a structure including a head part composed of an electron-rich atom and an aromatic ring having a high affinity for the carbon nanotube and a tail part having an affinity for a dispersion medium, and thus exhibits excellent stabilizing and dispersing effects of the carbon nanotube in a variety of dispersion media including organic solvents, water or mixtures thereof. Use of the dispersant in accordance with the present invention enables convenient preparation of carbon nanotube compositions necessary for a variety of industrial fields such as emitters of field emission displays (FEDs), carbon nanotube inks, printable carbon nanotubes and the like.
    • 提供了一种用于碳纳米管的分散剂及包含该分散剂的组合物,其中分散剂包括由富含电子的原子构成的头部和对碳纳米管具有高亲和力的芳环和尾部的结构 对分散介质具有亲和性,因此在包括有机溶剂,水或其混合物的各种分散介质中表现出优异的碳纳米管的稳定和分散作用。 使用根据本发明的分散剂可以方便地制备各种工业领域所需的碳纳米管组合物,例如场发射显示器(FED)的发射体,碳纳米管油墨,可印刷的碳纳米管等。

    • Disclosed is a polyester conjugated yarn, including two types of polymers having a large intrinsic viscosity difference subjected to bi-component spinning so as to be longitudinally arranged in a side-by-side sectional structure, in which the twp types of polymers are polyethyleneterephthalate having intrinsic viscosity of 0.45-0.65 as a first polymer and polytrimethyleneterephthalate having intrinsic viscosity of 0.90-1.10 as a second polymer. The polyester conjugated yarn is advantageous in terms of superior spinnability and high uniformity index. In addition, the polyester conjugated yarn can exhibit high self-crimping properties through relaxation-heat treatment of the dyeing and finishing process, and as well, can be applied to manufacture woven/knit fabrics having softness to the touch, beautiful colors, and high drapery and bulk properties, due to inherent characteristics of polytrimentyleneterephthalate.
    • 公开了一种聚酯复合纱线,其包括两种类型的具有特征粘度差的聚合物,其经受双组分纺丝以纵向布置成并排剖面结构,其中twp类型的聚合物是聚对苯二甲酸乙二醇酯,其具有 作为第一聚合物的特性粘度为0.45-0.65,特性粘度为0.90-1.10的聚三亚甲基对苯二甲酸酯作为第二聚合物。 聚酯复合纱在优异的可纺性和高均匀性指数方面是有利的。 此外,聚酯复合纱可以通过染色和整理过程的松弛热处理显示出高的自卷曲性,并且还可以应用于制造具有触感柔软度,美丽的颜色和高度的编织/针织织物 由于聚对苯二甲酸对苯二甲酸酯的固有特性,帷幔和散装性能。
