- •
In this study thin regenerated cellulose films were prepared by hydrolysis of cellulose acetate.
- •
Polyethylenimine and virus adsorption onto the films was studied by QCM-D.
- •
A regular growth of the PEI films was observed upon successive increases of the PEI concentration.
- •
The adsorption of T4D bacteriophages are 15-fold more efficient onto the PEI-treated film.
- •
PEI-functionalized cellulose-based highly improved the airborne virus affinity.
