Biopolymer chitosan was incorporated into a thin multiwalled carbon nanotube membrane (MWNT buckypaper) via filtration and soaking in 0.1% (w/v) of low‐molecular‐weight (MW) chitosan. The properties of the buckypaper membrane before and after annealing and after soaking were characterized by measurement of their electrical conductivities (19 ± 2 to 42 ± 2 S/cm), contact angles (31 ± 4° to 71 ± 4°), and mechanical properties (tensile strength, small‐ranging between 1.4 ± 0.1 and 4.2 ± 0.7 MPa; Young's modulus: 85 ± 4 to 443 ± 20 MPa). Moreover, the morphological properties, surface area, and permeability toward water of these buckypaper membranes were characterized and compared with corresponding carbon nanotube membranes prepared with Triton X‐100 (Trix) as the surfactant. Scanning electron microscopic (SEM) images and Brunauer, Emmett, and Teller (BET) data of MWNT‐annealing buckypaper membranes revealed that the diameters of their surface pores were significantly higher than that of the corresponding buckypaper membranes soaked in chitosan solution. The solution of chitosan incorporated inside the porous structure of the annealed MWNT membrane led to a significantly reduced surface area and pore size distribution of the composite membrane, revealing that this could be a useful method for desalination.

壳聚糖浸渍碳纳米管制成的巴克纸的制备与表征。

通过过滤并浸泡在0.1％（w / v）的低分子量（MW）壳聚糖中，将生物聚合物壳聚糖掺入了薄壁多壁碳纳米管薄膜（MWNT buckypaper）中。通过测量其电导率（19±2至42±2 S / cm），接触角（31±4°至71±4°）和机械特性来表征Buckypaper膜在退火前后和浸泡后的性能。性能（抗拉强度，范围在1.4±0.1至4.2±0.7 MPa之间;杨氏模量：85±4至443±20 MPa）。此外，表征了这些巴基纸膜的形态特性，表面积和对水的渗透性，并与以Triton X-100（Trix）作为表面活性剂制备的相应碳纳米管膜进行了比较。扫描电子显微镜（SEM）图像和Brunauer，Emmett，MWNT退火巴基纸膜的Teller和Teller（BET）数据表明，其表面孔的直径显着高于浸泡在壳聚糖溶液中的相应巴基纸膜的直径。掺入到退火的MWNT膜的多孔结构内部的壳聚糖溶液导致复合膜的表面积和孔径分布显着减小，这表明这可能是一种有用的脱盐方法。
