Composite hydrogels consists of three-dimensional networks, mainly of hydrophilic polymers. In our study we have used cellulose nanofibrils, which are a renewable, sustainable and “green” biomaterial obtained from wood. In combination with other biomaterials (e.g. alginate from marine brown algae), promising composite hydrogels can be produced. Composite hydrogels have many interesting application areas, and can be suggested for use in e.g. medical applications as tissue engineering and drug delivery. Structure-function relationships in the composite hydrogels are of interest, and it is of current interest to see if interactions between different biomaterials give improved hydrogels. Mechanical properties, rheological properties, diffusion properties and swelling / syneresis are relevant parameters in this study.
