Abstract

Controlled incorporation of carbon nanotubes (CNT) with alumina (AlO) and zirconia (ZrO) nanoparticles using an electrostatic nano-assembly method for the fabrication of homogeneous CNT-incorporated AlO-ZrO and CNT-incorporated shell-layer AlO-ZrO composite granules is demonstrated. The spark-plasma-sintered CNT-incorporated shell-layer AlO-ZrO artifact exhibited approximately 15 times higher electrical conductivity than a homogeneous CNT-incorporating artifact. This novel composite granule fabrication method using an electrostatic integrated assembly of colloidal nanomaterials would be beneficial for the development of multiscale and multicomponent composite materials.

摘要

本文展示了一种通过静电纳米组装方法将碳纳米管（CNT）与氧化铝（AlO）和氧化锆（ZrO）纳米颗粒进行可控结合，以制备均匀的含碳纳米管AlO-ZrO以及含碳纳米管壳层AlO-ZrO复合颗粒的方法。火花等离子烧结的含碳纳米管壳层AlO-ZrO制品的电导率比均匀含碳纳米管的制品高出约15倍。这种利用胶体纳米材料静电集成组装的新型复合颗粒制造方法将有利于多尺度和多组分复合材料的开发。
