Two types of carbon nanotube (CNT) based films were fabricated by adsorbing two different types of multiwalled carbon nanotubes (MWCNTs) on bacterial cellulose membrane templates. A bacterial cellulose membrane consists of ribbon-shaped nanofibrils that are arranged to form a porous 3D network. These characteristics lead to the uniform deposition of MWCNTs on the membrane structure and the final CNT based films with high surface areas. Two types of MWCNTs were used: (1) MWCNTs that had been purified by an acid treatment and (2) Ag-doped MWCNTs, which consisted of MWCNTs with Ag nanoparticles attached to their surfaces. The morphologies of the Ag-doped MWCNTs and CNT based films were examined using transmission electron microscopy. In addition, the electrical conductivity and electrochemical properties of the CNT based films were measured using a four-point probe and a cyclic voltammeter, respectively. The cyclic voltammetry data showed that the Ag particles attached to the MWCNT surfaces influenced the electrochemical properties of the CNT based films.
通过将两种不同类型的多壁碳纳米管（MWCNT）吸附在细菌纤维素膜模板上，制备了两种基于碳纳米管（CNT）的薄膜。细菌纤维素膜由带状纳米纤维组成，这些纳米纤维排列形成多孔的三维网络。这些特性导致MWCNT在膜结构上均匀沉积，并最终形成具有高表面积的基于CNT的薄膜。使用了两种类型的MWCNT：（1）经过酸处理纯化的MWCNT和（2）银掺杂的MWCNT，其由表面附着有银纳米颗粒的MWCNT组成。使用透射电子显微镜检查了银掺杂的MWCNT和基于CNT的薄膜的形态。此外，分别使用四点探针和循环伏安仪测量了基于CNT的薄膜的电导率和电化学性质。循环伏安法数据表明，附着在MWCNT表面的银颗粒影响了基于CNT的薄膜的电化学性质。
