Application Guidelines
Recommended Dosage
For small-scale trials, an initial loading of 0.2–3 wt%, based on the dry weight of the matrix, is recommended.
Addition Method
The material can be incorporated into pulp, packaging materials, water-based resins, and other biobased composite systems.
Dispersion Method
Mechanical stirring or high-speed shear mixing is recommended. For high-solids systems, gradual batchwise addition is recommended.
Precautions
The presence of lignin may affect color, transparency, hydrophilicity/hydrophobicity, and interfacial properties. These factors should be evaluated comprehensively according to the requirements of the end application.
Small-Scale Trial Recommendations
Key performance parameters to compare include reinforcement, UV barrier performance, water absorption, color, and film-forming properties.

FAQ
Q: What is the difference between lignin-containing CNF and conventional CNF?
A: Lignin-containing CNF retains a certain proportion of lignin-related components. In addition to the inherent reinforcement characteristics of nanocellulose, it may therefore exhibit different color, surface chemistry, UV absorption, and interfacial properties.
Q: How does lignin affect the dispersion and optical properties of nanocellulose?
A: The lignin content and distribution can alter surface chemistry, hydrophilicity/hydrophobicity, and color, thereby potentially affecting dispersion, transparency, and UV absorption. These properties should be evaluated based on characterization of the specific batch.
Q: Is lignin-containing CNF suitable for biobased packaging and functional films?
A: It is suitable for research into biobased composites, packaging, functional films, and UV-shielding applications. However, for light-colored or highly transparent applications, color and light transmittance should be evaluated in advance.
Q: What properties should be prioritized when evaluating lignin-containing CNF in composite materials?
A: It is recommended to evaluate dispersion, reinforcement performance, interfacial morphology, color, UV-shielding performance, and water absorption/water resistance in parallel to assess the overall effects of lignin retention.
