Non-covalent functionalisation of the carbon nanotube (CNT) sidewall through polymer wrapping is the key strategy for improving well-dispersed CNTs without persistent alteration of their electronic properties. In this work, the effect of reaction time on regioregular poly (3-hexylthiophene-2,5-diyl) (P3HT)-wrapped hydroxylated multi-walled CNT (MWCNT-OH) nanocomposites was investigated. Five different reaction times (24, 48, 72, 96, and 120 h) were conducted at room temperature in order to clearly determine the factors that influenced the quality of wrapped MWCNT-OH. Morphological analysis using Field Emission Scanning Electron Microscopic (FESEM) and High-Resolution Transmission Electron Microscope (HRTEM) analysis showed that P3HT successfully wrapped the MWCNT-OH sidewall, evidenced by the changes in the mean diameter size of the nanocomposites. Results obtained from Raman spectroscopy, X-ray Photoelectron Spectroscopy (XPS) as well as Thermogravimetric Analysis (TGA) showed a significant effect of the wrapped polymer on the CNT sidewall as the reaction time increased. Overall, the method used during the preparation of P3HT-wrapped MWCNT-OH and the presented results significantly provided a bottom-up approach to determine the effect of different reaction times on polymer wrapping to further expand this material for novel applications, especially chemical sensors.
通过聚合物包裹对碳纳米管（CNT）侧壁进行非共价功能化是提高碳纳米管良好分散性且不持久改变其电子性能的关键策略。在这项工作中，研究了反应时间对区域规整聚（3-己基噻吩-2,5-二亚基）（P3HT）包裹的羟基化多壁碳纳米管（MWCNT-OH）纳米复合材料的影响。在室温下进行了五个不同的反应时间（24、48、72、96和120小时），以便明确确定影响包裹的MWCNT-OH质量的因素。使用场发射扫描电子显微镜（FESEM）和高分辨率透射电子显微镜（HRTEM）分析进行的形态学分析表明，P3HT成功包裹了MWCNT-OH的侧壁，纳米复合材料平均直径尺寸的变化证明了这一点。从拉曼光谱、X射线光电子能谱（XPS）以及热重分析（TGA）获得的结果表明，随着反应时间的增加，包裹的聚合物对碳纳米管侧壁有显著影响。总体而言，制备P3HT包裹的MWCNT-OH期间使用的方法以及所呈现的结果显著提供了一种自下而上的方法，以确定不同反应时间对聚合物包裹的影响，从而进一步将这种材料扩展用于新的应用，特别是化学传感器。
