Abstract:
A new biobased material based on an original strategy using lignin model compounds as natural grafting additive on a nanocellulose surface through in situ polymerization of coniferyl alcohol by the Fenton reaction at two pH values was investigated. The structural and morphological properties of the materials at the nanoscale were characterized by a combination of analytical methods, including Fourier transform infrared spectroscopy, liquid chromatography combined with mass spectrometry, nuclear molecular resonance spectroscopy, electron paramagnetic resonance spectroscopy, water sorption capacity by dynamic vapor sorption, and atomic force microscopy (topography and indentation modulus measurements). Finally, the usage properties, such as antioxidant properties, were evaluated in solution and the nanostructured casted films by radical 2,2'-diphenyl-1-picrylhydrazyl (DPPH•) scavenging tests. We demonstrate the structure-function relationships of these advanced CNC-lignin films and describe their dual functionalities and characteristics, namely, their antioxidant properties and the presence of persistent phenoxy radicals within the material.
