Increasing wet adhesion between cellulose surfaces with polyvinylamine

The conditions are elucidated whereby strong adhesive joints between two wet cellulose surfaces can be achieved with a polyelectrolyte adhesive. Adhesion results were obtained with wet, TEMPO oxidized, regenerated cellulose membranes that were laminated with polyvinylamine (PVAm) adhesive. Wet adhesion was determined as the 90° wet-peel delamination force. Aldehyde groups on the oxidized cellulose form imine and aminal covalent linkages with …
