Bovine Serum Albumin (BSA) as an adhesive for wet cellulose

Regenerated cellulose films were laminated using very thin layers of the protein Bovine Serum Albumin (BSA) as an adhesive. The wet delamination strength was measured as functions of pH, lamination time, temperature and pressure, as well as cellulose oxidation. Drying at elevated temperature (120 °C) was required for strong adhesion. Oxidation of the cellulose membranes to introduce surface carboxyl/aldehyde groups increased the wet …
