“…As it was shown previously, an initial electrochemical oxidation of adsorbed lignins results in the de-methylation of free omethoxyphenyl moieties contained in the macromolecule that produces o-quinone [17,18]. The latter can be reversibly cycled between the oxidized (Q) and reduced (QH 2 ) form.…”

“…This means that the composite provides at least a 0.3 V reduction of the reaction overpotential comparing with an unmodified electrode. The magnitudes of the redox peaks and catalytic NADH oxidation currents recorded on MWCNT/KL modified electrodes are 50-100 times higher than on the KL-modified GC electrodes lacking MWCNT at comparable experimental conditions [17,18]. This is likely due to the intimate contact of lignin-derived redox moieties with a 3D MWCNT scaffold facilitating the charge transport.…”

There is a need for renewable resources as a raw material for commodity polymers. Lignin is one of the most important natural biopolymers from renewable resources due to its suffi cient supply, robust material properties and the fact that its use does not compete with the food supply. Lignin has been investigated since the late 19th century, but its applications are limited due to poor processability, low reactivity and intrinsic heterogeneity depending on the plant source and isolation methods used. Current strategies for using lignin in modern materials center on integrating it with other natural or synthetic polymers. This review article introduces the technological importance of lignin and focuses on copolymers and blends based on lignin in a broad range of applications.
