We report a simple and rapid method to prepare multifunctional free-standing single-walled carbon nanotube (SWCNT) films with variable thicknesses ranging from a submonolayer to a few micrometers having outstanding properties for a broad range of exceptionally performing devices. We have fabricated state-of-the-art key components from the same single component multifunctional SWCNT material for several high-impact application areas: high efficiency nanoparticle filters with a figure of merit of 147 Pa(-1), transparent and conductive electrodes with a sheet resistance of 84 Ω/◻ and a transmittance of 90%, electrochemical sensors with extremely low detection limits below 100 nM, and polymer-free saturable absorbers for ultrafast femtosecond lasers. Furthermore, the films are demonstrated as the main components in gas flowmeters, gas heaters, and transparent thermoacoustic loudspeakers.
我们报告了一种简单快速的方法来制备具有可变厚度的多功能独立式单壁碳纳米管（SWCNT）薄膜，厚度从亚单层到几微米不等，具有广泛的卓越性能，适用于各种特殊性能的器件。我们已经从同一种多功能单组分 SWCNT 材料制造出了最先进的关键组件，用于几个高影响力的应用领域：具有 147 Pa(-1) 的优异品质因数的高效纳米颗粒过滤器、具有 84 Ω/◻ 的方阻和 90%透光率的透明导电电极、检测限低至 100 nM 以下的电化学传感器以及用于超快飞秒激光器的无聚合物可饱和吸收体。此外，这些薄膜还可用作气体流量计、气体加热器和透明热声扬声器的主要组件。
