研究目的
To improve the sorting yield of large-diameter semiconducting single-walled carbon nanotubes (s-SWCNTs) with high purity using a mixed-extractor strategy.
研究成果
The mixed-extractor strategy significantly enhances the sorting yield of large-diameter s-SWCNTs with high purity, showing a preference for (15,4) SWCNTs. This method is scalable and efficient, suitable for large-area fabrication of high-performance SWCNTs-based electronic devices.
研究不足
The study focuses on the sorting of large-diameter s-SWCNTs using a specific mixed-extractor strategy. The scalability and applicability of this method to other types of SWCNTs or under different conditions were not explored.
1：Experimental Design and Method Selection:
The study employs a mixed-extractor strategy involving two conjugated polymers with different rigidity, PDFP and P8BT, for sorting large-diameter s-SWCNTs through two simple sonication processes.
2：Sample Selection and Data Sources:
Arc-discharge SWCNTs with diameters of 1.2–1.6 nm were used. The polymers P8BT and PDFP were dissolved in toluene for the sorting process.
3：2–6 nm were used. The polymers P8BT and PDFP were dissolved in toluene for the sorting process.

4：0).
Experimental Procedures and Operational Workflow:
4. Experimental Procedures and Operational Workflow: The process involves dispersing SWCNTs with P8BT, adding PDFP, sonicating, and centrifuging to collect the supernatant for analysis.
5：Data Analysis Methods:
UV/Vis-NIR absorption spectra, Raman spectroscopy, and PL excitation maps were used to analyze the sorted s-SWCNTs.
