Abstract
This work focused on an eco-friendly and facile method to produce lignocellulose nanofibrils (LCNFs) by the one-step grinding of original poplar wood. An array of detailed characterizations were performed to elucidate the effect of the residual lignin (22.1, 14.1, 8.2, 2.0, 0.4 and 0.2%) on the properties of LCNFs and its films. The LCNFs were rather sensitive to ultraviolet absorption, low-viscosity and anti-degradation properties. Morphological observations suggested that lignin particles homogeneously attach to the surface of cellulose nanofibrils for higher-residual-lignin samples. The results of chemical structures analysis demonstrated an effect of residual lignin amounts on the CrI. Further, the LCNF nanofilms exhibited enhanced hydrophobicity and mechanical properties. Overall, LCNFs are a renewable material with low environmental impact, low cost and they are being manufactured at a largescale. They also offer potential for a wide range of applications, such as ultraviolet protection, anti-degradation, and valuable reinforcing composite materials.
