Water dispersible nanofibrilar polyaniline (NF-PANI) provides a novel and direct route towards carbon nanotube water dispersions of high concentration. Carrying out the chemical synthesis of NF-PANI in the presence of carbon nanotubes (CNTs) results in an entirely nanostructured nanofibrilar polyaniline/carbon nanotube (NF-PANI/CNT) composite material that contains well segregated CNTs partially coated by NF-PANI. This new approach is simple, fast, and inexpensive, and enables the direct preparation of stable and homogeneous dispersions of the composites in water at concentrations up to 10 mg · mL(-1) , even for the highest CNT loadings of 50 wt.-% without the participation of surfactants or stabilizers.
水分散性纳米纤维聚苯胺(NF-PANI)为制备高浓度碳纳米管水分散体提供了一条新颖且直接的途径。在碳纳米管(CNT)存在的情况下进行NF-PANI的化学合成,会得到一种完全纳米结构的纳米纤维聚苯胺/碳纳米管(NF-PANI/CNT)复合材料,其中包含被NF-PANI部分包覆且分布良好的CNT。这种新方法简单、快速且成本低廉,能够直接制备浓度高达10 mg·mL⁻¹的复合材料在水中的稳定均匀分散体,即使对于高达50 wt.-%的最高CNT负载量,也无需表面活性剂或稳定剂的参与。
