Abstract

A simple continuous flow wet-spinning method for assembling fibres consisting of two oppositely charged biopolymers (chitosan and carrageenan) and carbon nanotubes is reported. It was observed that the order in which the biopolymers are added, i.e. spinningchitosan into one of the carrageenans (or vice versa), affects the fibre composition as well as the resulting electrical and mechanical properties. The addition of carbon nanotubes into the fibres was found to improve Young's modulus values coupled with a significant improvement in the electrical conductivity by up to 6 orders of magnitude.
