Modification of CFs and the extent of improvement.

Type	Method	CFs	Extent of improvement	Ref.
Physical modification	Polyelectrolyte adsorption	Blue eucalyptus paper	Antibacterial effect	[91]
	Nonelectrolyte adsorption	Cellulose nanocrystals	Changed the surface structure and properties of cellulose	[92]
Chemical modification	Small molecule modification	Pulp	Promoted the preparation of nanocellulose	[93]
	Graft modification	Softwood cellulose fiber	Formed a strong nanocomposite	[94]
	Cross-linking modification	Cellulose nanocrystals	Improved thermal stability and water resistance, decreased swelling degree	[95]
Biological modification	In situ modification	6-Carboxyfluorescein-modified glucose	With nonnatural characteristic fluorescent function	[96]
	Ex situ modification	Proanthocyanidins as cross-linking agent	Novel bacterial cellulose/gelatin composite	[97, 98]
