我们制备了不同浓度的银纳米颗粒（Ag NP）修饰的单壁碳纳米管（SWCNT）薄膜。由1.0wt%Ag NP浓度修饰的Ag-NP/SWCNT膜的典型SEM照片表明，具有10-nm直径的Ag NP附着于纳米管束的表面，并且附着于纳米管的Ag NP的数量约为40 - 60个颗粒/μ m。在氮气下在723 K下退火后，烧结的Ag颗粒在1.0重量% Ag-NP/SWCNT膜中覆盖整个膜上的纳米管束。薄膜的面内电导率随着Ag NP浓度的增加而增加，从2.55 × 103 S/m增加到5.06 × 103 S/m。
We prepared single‐walled carbon nanotube (SWCNT) films decorated by various silver nanoparticle (Ag NP) concentrations. Typical SEM photographs of Ag‐NP/SWCNT films decorated by a 1.0wt% Ag NP concentration indicated that Ag NPs with a 10‐nm diameter attached to the surface of nanotube bundles, and the number of Ag NPs attached to the nanotubes was roughly 40∼60 particles/µm. After annealing at 723 K under nitrogen gas, sintered Ag particles covered the nanotube bundles all over the film in 1.0wt% Ag‐NP/SWCNT films. The in‐plane electrical conductivities of films had a tendency to increase with increasing Ag NP concentration, from 2.55×103 to 5.06×103 S/m.
