(Semi)-quantitative approach to assess the ability of self-standing nanocellulose films to collect nano- and microplastics.

Fluorescence spectroscopy

Elucidate the capturing mechanisms, i.e. whether electrostatic interactions play a role along with the nanocellulose network hygroscopicity.

Particle specificity

  1. Main finding: Hygroscopic TEMPO-CNF film performs the best and attractive electrostatic interactions seem to have a more pronounced role when dealing with ø 1µm particles. Capture of particles is not dependent on the particle type.
