Layer-by-layer electrostatic selfassembly of anionic and cationic carbon nanotubes

The layer-by-layer(LBL) self assembly of anionic and cationic multi-walled carbon nanotubes(MWNTs) through electrostatic interaction has been carried out to fabricate all-MWNT multilayer films.The alternate uniform assembly of anionic and cationic MWNTs was investigated by UV-vis spectroscopy.Scanning electron microscopy(SEM) images displayed the growth of the MWNT films.

Synthesis and aggregation properties of amphiphilic mono and bisadducts of fullerene in aqueous solution

新 amphiphilic [60 ] fullerene monoadduct TPF 和 bisadducts BTPF 被综合并且描绘得好。他们在水的答案的聚集性质被紫外鈥搗i s 和 TEM 方法调查。在水的答案，不规则地塑造的 monoadduct TPF 形式和一些像杆的总数，而 bisadducts BTPF 与 50 鈥 ? 的直径给球形的总数 50 nm。它显示 amphiphilic fullerene 衍生物的聚集性质在 C60 笼子上取决于吸水的附器的数字。
