Interaction in cellulosic fiber-fiber joints at humid and wet conditions by AFM and confocal Raman microscopy

摘要

1. Interaction forces in crossed cellulosic fiber joints between was explored by atomic force colloidal probe microscopy (AFM) in dry and humid air, and in water a. Extent, range and type of interaction in comparison with literature and calculated values for extent and range 2. Confocal Raman microspectroscopy (CRM) imaging for surfaces and joints on thermomechanical pulp fibers, bleached pulp fibers and rayon fibers a. To image chemical and structural constituents relevant for bonding at high enough resolution b. To detect differences due to stresses or strains at, or close to, the fiber-fiber bonded area.
