| Abstract: |
| Polyvinylpyrrolidone （PVP） and laponite were used as dispersants to reduce the viscosity of cellulose nanofiber （CNF） aqueous dispersion during preparation precess of cellulose nanostructured paper （CNP）. Compared to the CNP without adding PVP and laponite， the formation time of CNP with 0.4% PVP and 0.3% laponite was reduced from 135 to 48 min， its transmittance increased from 82.0% to 90.3%， and density decreased by 63.6%， mean roughness （Ra） and root mean square roughness（Rq） decreased by 69.7% and 69.1%， respectively. |
