Fibre – Water

  • KTH course
The interactions of water with cellulose-based materials from a thermodynamic and polymer physical perspective, and its effect on mechanical properties and final performance of fibre based networks.

Course content:

• Fibre, paper and water interactions: Problem specification, and importance.

• Thermodynamics of water vapour adsorption to fibres

• Swelling of polyelectrolyte gels and cellulose fibres

• The influence of moisture on mechanical properties of fibre compositions, papers and films and their outcome performance

• Fundamentals of wetting, capillary penetration and superhydrophobicity

• Liquid absorption in hygiene products

Learning objectives:

After completion of the course the doctoral student should:

  • Have good knowledge and overview of the basic processes that control the interaction of water with cellulose-based materials.
  • Have overall understanding of the impact of wetting, absorption and swelling on porous fiber networks.
  • Be able to define the basic mechanisms that control interactions (wetting, absorption, swelling) both from a thermodynamic and polymer physical perspective.
  • Have planned and carried out the course independently in order to pass the exam, and be able to critically evaluate one's own and others' results from a scientific point of view.
