The influence if the ageing process on the paper surface topography has been examined by means of the Atomic Force Microscopy (AFM). The AFM images of thr native and artificially aged paper exhabit different surface strucure and various abilities to bond water. The surface of native paper consist of the cellulose macrofibres with a spine-like structure, and the elementary fibres of about 10 ÷ 20 nm in diameter. It was found that the ageing process did not change the spine-like structure of the cellulose macrofibres, although it induced the swelling of the elementary fibres. In addition, the images of the aged paper showed that multilayers of water were formed on its surface whereas for non-aged samples such effect was not observed. This behaviour was confirmed by using a technique of "phase-imaging". We argue that swelling of the cellulose fibres and formation of water multilayers is caused by water molecules which are permanently bound to the cellulose chains of the aged paper.
