The current problems in the nanocellulose industry

Currently, nanocellulose still faces some challenges and problems in its preparation and application, including but not limited to:

1. Preparation technical issues:

Efficient extraction and purification: Efficient extraction of from natural sources (such as plant fibers, ligno fibers) nanocellulose and efficient purification remains a challenge, as cellulose is often associated with other components (such as hemicellulose, lignin, etc.) Mixed existence.

Control of nanocellulose crystallinity: The crystallinity of nanocellulose directly affects its performance and application. How to control the crystal structure and morphology of cellulose still needs further research.

Improved solubility and dispersion: The solubility and dispersion of nanocellulose in water or organic solvents need to be improved to improve its application in coatings, composite materials and other fields.

2. Application technical issues:

Processing performance optimization: The processing performance of nanocellulose as a raw material in the fields of nanocomposite materials, biomedical products, etc. needs to be further optimized to achieve wider application.

Multifunctional design: How to achieve its multifunctional application in different fields by changing the structural and surface properties of nanocellulose remains a challenge.

Industrialization problems: The large-scale production and industrial application of nanocellulose face challenges in cost, technology and marketing, and requires interdisciplinary cooperation and continuous investment.

3. New technologies and new applications development:

Application of nanocellulose in emerging fields: such as biomedicine, energy storage, environmental governance, etc., the application potential of nanocellulose is huge, but new technologies and new applications are needed.

To sum up, there are still many problems and challenges in the preparation and application technology of nanocellulose, and scientists and engineers need to carry out continuous research and innovation in the fields of materials science, chemical engineering, biotechnology, etc. to promote nanofibers. further development and application of material technology.
