Defectless and Uniform Single-Crystallite Dispersions of Sustainable Wood Nanocellulose with a Regulated Right-Handed Twist Periodicity.

Abstract in brief

• This study demonstrates that selecting specific raw materials (softwood pulp and holocellulose) and applying targeted chemical pretreatment can effectively suppress defects in cellulose nanofibers (CNFs), leading to uniform, defect-free single crystallite dispersions.
• Using atomic force microscopy (AFM) and wavelet transform analysis, the researchers confirmed that the resulting CNFs are highly uniform with a regulated twist periodicity, which is important for consistent material properties.
• The findings highlight the importance of controlling the nanoscale supramolecular structure of plant cellulose during production, paving the way for higher quality, sustainable wood nanocellulose useful in advanced applications.]
