“…First of all, in the range of the interaction, the onset of repulsive forces according to our observation never exceeds 25 nm. This corresponds to results reported by Rutland and co-workers [4,5] in studies of the interaction between two cellulose spheres. Whereas in measurements carried out by Zauscher and Klinberg using a cellulose film and sphere [8] the onset of repulsive forces reached almost 100 nm at low ionic strength (0.1 mM NaCl).…”

“…The force-distance profiles obtained in this study are generally consistent with AFM or SFA studies of the cellulose/cellulose interaction [4][5][6][7][8]. The influence of electrolyte concentration on the force-distance profiles signifies the importance of the electrostatic interactions for cellulose surfaces (Fig.…”

“…These techniques have been used to measure interactions of cellulose surfaces [4][5][6][7][8][9] aiming mostly to increase the insight into interfacial phenomena in traditional cellulose applications such as papermaking. With growing interest in new cellulose applications often involving biomolecules or even cells and tissues (drug delivery devices [10], affinity separation [11], tissue engineering [12]) surface force measurements are becoming important to advance understanding of interfacial phenomena in such complex multi-component systems based on cellulose polymers.…”

Colloidal probe microscopy has been used to study the interaction between model cellulose surfaces and the role of cellulose binding domain (CBD), peptides specifically binding to cellulose, in interfacial interaction of cellulose surfaces modified with CBDs.The interaction between pure cellulose surfaces in aqueous electrolyte solution is dominated by double layer repulsive forces with the range and magnitude of the net force dependent on electrolyte concentration. AFM imaging reveals agglomeration of CBD adsorbed on cellulose surface. Despite an increase in surface charge owing to CBD binding to cellulose surface, force profiles are less repulsive for interactions involving, at least, one modified surface. Such changes are attributed to irregularity of the topography of protein surface and non-uniform distribution of surface charges on the surface of modified cellulose.Binding double CBD hybrid protein to cellulose surfaces causes adhesive forces at retraction, whereas separation curves obtained with cellulose modified with single CBD show small adhesion only at high ionic strength. This is possibly caused by the formation of the cross-links between cellulose surfaces in the case of double CBD.

“…[50][51][52] In the case of the present LB-cellulose, the only likely source of negative charge is carboxyl groups since the pK a of other possible sources, e.g., sugar alcoholic groups and hemiacetal OH groups is above 12. 53 Findings on other model cellulose surfaces, e.g., spin-coated cellulose (prepared from microcrystalline cellulose) studied by surface force techniques 54,55 and type II cellulose studied by scanning probe microscopy 56 support the thesis of a charged cellulose surface. …”

X-ray photoelectron spectroscopy was used to estimate the absolute amount of cationic polyelectrolytes that adsorbs on mica and cellulose surfaces in aqueous media. The calculation takes advantage of the knowledge of the mica crystal composition at the basal plane and its ion-exchange properties in aqueous solution. The XPS was operated under monochromatic and unmonochromatic mode and good agreement was observed in the resulting adsorbed amount. The evaluation of the amount of cationic polyelectrolyte adsorbed on cellulose was achieved using calibration curves obtained from adsorption data for the same polyelectrolytes on bare mica surfaces. The adsorption isotherm for polyelectrolytes of low charge density adsorbed on cellulose reveals that their affinity toward cellulose is weaker compared to that observed for highly charged surfaces such as mica. The effect of the polyelectrolyte charge density on the adsorbed amount and the number density of charged segments adsorbed on cellulose were also investigated. From these results it can be concluded that nonelectrostatic interactions are the main contributors to the adsorption of polyelectrolytes on cellulose, but it cannot be ruled out that electrostatic effects also take part in the adsorption mechanism. Finally, it is demonstrated that it is not correct to use the adsorbed amount of polyelectrolytes to determine the surface charge on cellulose surfaces.

“…The adhesion between paper and other materials are also of great importance; inorganic fillers are commonly used in paper, ink has to adhere during the printing process (and be removed during deinking), and paper and other materials are used together in composites such as packing materials for food. For these reasons interactions forces acting between cellulose surfaces and between cellulose and other materials have been studied extensively during the last years using a range of surface force methods such as atomic force colloidal probe [2][3][4], MASIF [5] and the interferometic surface force apparatus, SFA [6][7][8]. These techniques are all very powerful and they provide information of long-range and adhesive properties between surfaces.…”
