Supercritical carbon dioxide: A powerful tool in biopolymer processing

  • Drying of ultra-lightweight open-porous soft materials aiming at full retention of pore features
  • Loading of porous materials with bioactive compounds by scCO2 antisolvent precipitation
  • Purification and controlled precipitation of hemicellulose microparticles
  • Utilization of scCO2 as a reactant and solvent for polymerization and derivatization
