A supramolecular assembly of amylose and single-walled carbon nanotubes (SWNTs) was synthesized in situ through vine-twining polymerization. Raman analysis indicated that the amylose-SWNTs supramolecular assembly was formed after the polymerization and SEM images displayed the twisted ribbons in the SWNTs wrapped by amylose. The dispersion stability of the SWNTs in aqueous solutions was improved by the wrapping of short-chain amylose molecules around the SWNTs.
通过藤蔓缠绕聚合原位合成了直链淀粉与单壁碳纳米管（SWNTs）的超分子组装体。拉曼分析表明，聚合后形成了直链淀粉 - SWNTs超分子组装体，扫描电子显微镜图像显示直链淀粉包裹的SWNTs呈现出扭曲的带状结构。短链直链淀粉分子围绕SWNTs的包裹提高了SWNTs在水溶液中的分散稳定性。
