利用简单、可扩展的浸渍涂层在黄麻纤维或织物表面沉积多壁碳纳米管（MWCNTs），可实现具有传感能力的黄麻纤维和相应的环氧基复合材料。在黄麻纤维表面形成了电半导体MWCNT网络，这反过来又导致黄麻/环氧界面形成了高浓度的MWCNT。进一步详细确定了MWCNT涂层黄麻纤维和黄麻/环氧复合材料对温度、相对湿度和应力/应变的传感行为，这些行为受到纤维固有物理和化学特性的强烈影响。此外，与纯黄麻/环氧复合材料相比，mwcnt -黄麻/环氧复合材料的介电性能有显著改善。基于这种方法，电绝缘的天然纤维和表面具有半导体性质的MWCNTs将激发并实现广泛的多功能应用。
Jute fibres and corresponding epoxy based composites with sensing abilities could be realized by depositing multi-walled carbon nanotubes (MWCNTs) on the surfaces of jute fibres or fabrics using simple and scalable dip coating. The formation of electrically semiconducting MWCNT networks on jute fibre surfaces was confirmed, which in turn caused the formation of jute/epoxy interphases with highly concentrated MWCNTs. The sensing behaviour of the MWCNT coated jute fibres and jute/epoxy composites for temperature, relative humidity and stress/strain was further established in detail, which were strongly influenced by the intrinsic physical and chemical features of the fibres. In addition, a significant improvement in dielectric properties of the MWCNT-jute/epoxy composites was observed compared to neat jute/epoxy composites. Based on this approach, the electrically insulating natural fibres along with semiconducting MWCNTs on surface will stimulate and realize a broad range of multi-functional applications.
