一般描述

各 SWCNT 的平均直径 = 1.4nm ± 0.1nm

应用

在水中分散的方法: 在固体形式下,SWNTs在宏观粒子中高度缠结。打破这种关联并使得材料溶于溶液,需要付出巨大的努力。将50 mg材料在2 ml水中超声处理30 min。添加8 ml水,再超声处理90 min。通常,在该程序完成后,根据目视观察,所有材料均完全分散。对于溶解度的定量测量,让分散液在室温下静置过夜。 由于浓缩分散液的高光密度,将所研究分散液上层的等分试样稀释100倍。 根据记录的NIR光谱,使用9750 cm-1处与标准溶液浓度相比的吸光度图,估计稀释溶液的浓度(见参考文献)。

Poly(aminobenzene sulfonic acid) (PABS) and polyethylene glycol (PEG) were covalently attached to single-walled carbon nanotubes (SWNTs) to form water-soluble graft copolymers. Quantitative near-IR (NIR) spectroscopic studies of these SWNT graft copolymers indicate a water solubility of about 5 mg/mL, and

Carbon nanotubes are materials that possess remarkable properties and offer extraordinary possibilities.

Carbon nanotubes (CNTs) have received much attention since their discovery in 1991 by Sumio lijima1 due to their excellent mechanical, electrical, and optical properties.

A nanocomposite is typically defined as a mixture between a host material (e.g., polymer matrix) and nanofillers with at least one dimension of less than 100 nm.

SWCNTs show promise in FETs, solar cells, and photodetectors due to their ultrafast charge transport mobility.
