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 excellent selectivity toward (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 and may not be directly applicable to small-diameter SWCNTs. The process requires specific polymers and may not be universally applicable to all types of SWCNTs.
1：Experimental Design and Method Selection:
The study employs a mixed-extractor strategy involving two conjugated polymers with different rigidity, PDFP and P8BT, to sort 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 PDFP and P8BT were dissolved in toluene for the sorting process.
3：2–6 nm were used. The polymers PDFP and P8BT were dissolved in toluene for the sorting process.
List of Experimental Equipment and Materials:
3. List of Experimental Equipment and Materials: UV-2600 spectrophotometer, confocal Raman microscope, atomic force microscope (AFM), ultra speed centrifuge (Thermo scientific Sorvall WX100).
4：0).
Experimental Procedures and Operational Workflow:
4. Experimental Procedures and Operational Workflow: The mixture of SWCNTs and polymer solution was sonicated, centrifuged, and the supernatant was collected for optical characterization.
5：Data Analysis Methods:
UV/Vis-NIR spectra, Raman spectroscopy, and AFM were used to characterize the sorted s-SWCNTs.
