溶液等离子体处理（SPP）已在氨水溶液中对多壁碳纳米管（MWCNT）进行。 MWCNT 在水溶液中不分散，SPP 后均匀分散。只需 2 小时即可获得 10 克分散的多壁碳纳米管，而在之前的研究中获得 185 毫克分散的多壁碳纳米管需要 7 天和额外的化学品。 SPP处理的MWCNT的X射线光电子能谱和傅里叶变换红外光谱表明，MWCNT上形成了含氮和氧基团。在 SPP 处理的 MWCNT 的拉曼光谱或透射电子显微镜图像中没有观察到 MWCNT 结构的严重损坏。使用聚酰胺 6 与 SPP 处理的 MWCNT 制备的复合材料比使用未经处理的 MWCNT 制备的复合材料表现出更好的拉伸、弯曲和冲击强度。
Solution plasma processing (SPP) has been performed on multiwalled carbon nanotubes (MWCNTs) in ammonia aqueous solution. The MWCNTs, which do not disperse in aqueous solution, uniformly dispersed after the SPP. Only 2 h was required to obtain 10 g of the dispersed MWCNTs, while 7 days and additional chemicals were required for 185 mg in a previous study. The X-ray photoelectron spectroscopy and Fourier-transform infrared spectroscopy of the SPP-treated MWCNTs revealed that nitrogen- and oxygen-containing groups are formed on the MWCNTs. Serious damage to the MWCNT structure was not observed in the Raman spectrum or transmission electron microscopy images of the SPP-treated MWCNTs. The composite materials prepared using polyamide 6 with the SPP-treated MWCNTs showed better tensile, bending, and impact strength than those prepared with nontreated MWCNTs.
