Abstract [en]

To gain a more fundamental understanding of the mechanism for joint formation between pulp fibres, we have utilized the JKR approach to study the adhesion properties of multilayers formed using anionic and cationic MFC (microfibrillar cellulose). The effect of using anionic or cationic MFC in the outermost layer has been elucidated and compared with measurements performed on other types of cellulosic model surfaces. Furthermore, our JKR instrument has been modified to enable measurements of the drying process, by comparing the adhesion interaction between PVAm (poly[vinylamine]) coated surfaces that have been dried in contact, or dried before being brought into contact. The typical contact area in the JKR experiments are in the micrometre range and our measurements have been compared with nanoscale adhesion measurements by colloidal probe AFM (atomic force microscopy).
