    Abstract

    Development of novel high added value cellulose
    products requires improved understanding of interaction forces,
    which includes also the adhesion force, between cellulose
    surfaces. However, the interaction forces between cellulose
    surfaces have not been adequately studied. In this paper,
    cellulose-cellulose adhesion force is studied by using a
    customized dual-probe atomic force microscope (AFM) with a
    cellulose colloidal probe. Two different types of cellulose
    membranes (CM) with cellulose concentration of 1.5% and 2%
    are used as test samples, and about ten thousand tests are
    repeated on each CM sample type. Adhesion force histograms
    are provided and they show a large difference between the two
    types of CM. The average adhesion force on CM 1.5% is
    approximately 10 times higher than that on CM 2%. On CM
    1.5%, the adhesion forces concentrate on the range from 450nN
    to 650nN, whereas on CM 2% the force distribute from 50 to
    75nN. The difference in the adhesion force on these two types of
    CM can be attributed to their difference in surface roughness
    and surface energy.
