In this study,silver nanoparticles（AgNPs）were synthesized via hydrothermal method,and the AgNPs/nanocellulose composite （Ag-CNF）was prepared with TEMPO oxidized nanocellulose（TOCNF）as only carrier and dispersant,AgNO3 solution as the silver source. The effects of TOCNF content and Ag+ concentration on Ag-CNF properties were investigated. The results showed that the AgNPs synthe? sized with 1% TOCNF and Ag+ concentration of 10 mmol/L were evenly dispersed with no significant aggregation of large particles,of which the average particle size was 22. 3 nm. The diameter of inhibition zone were 2. 70 mm and 3. 50 mm for Escherichia coli（E. coli）and Staph? ylococcus aureus（S. aureus）,respectively,showing a good antibacterial performance. ? 2023 China Technical Association of Paper Industry.
