✦ Synopsis

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.
