Abstract MWCNTs@silk fabric (CSF) with single-side, good conductive property was prepared via a surface micro-dissolution strategy. In this method, the partial dissolution of silk fibers was regulated by the concentration formic acid and the interaction between the protein and its solvent. The dissolved silk protein served as the physical crosslinking agent that connected dispersed carbon nanoparticles to form a continuous conductive network, avoiding complex chemical treatments and the use of physical adhesives. CSF possessed good electrical conductivity (468 Ω cm−1) and durability. Moreover, CSF had a unique single-side loading characteristic and its resistance changed from 98.4% to 102% of the initial value with the bending angle varying from −112.5° to 112.5°, so CSF could be used as sensors to monitor the mechanical activities effectively. Patterned conductive MWCNTs@silk fabric (PCSF) was fabricated by using patterned templates during the deposition process and used for wider applications, such as flexible switches (F-shaped PCSF), soft keyboards (keyboard-like PCSF), electric heating materials (S-shaped PCSF) and microwave-assisted heating materials (butterfly-like PCSF).

用于机械传感器和加热材料的多壁碳纳米管功能化丝织物

摘要 通过表面微溶解策略制备了具有单面、良好导电性能的多壁碳纳米管@丝织物（CSF）。在该方法中，丝纤维的部分溶解受甲酸浓度和蛋白质与其溶剂之间的相互作用的调节。溶解的丝蛋白作为物理交联剂，将分散的碳纳米粒子连接起来形成连续的导电网络，避免复杂的化学处理和物理粘合剂的使用。CSF 具有良好的导电性 (468 Ω cm-1) 和耐用性。此外，CSF具有独特的单侧加载特性，随着弯曲角度从-112.5°到112.5°变化，其电阻从初始值的98.4%变为102%，因此CSF可作为传感器监测机械活动有效。
