General description
各 SWCNT 的平均直径 = 1.4nm ± 0.1nm
Application
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)。
