Abstract [en]

Friction force measurements have been conducted with a colloid probe on mica and silica (both hydrophilic and

hydrophobized) after long (24 h) exposure to high-humidity air. Adhesion and friction measurements have also been

performed on cellulose substrates. The long exposure to high humidity led to a large hysteresis between loading and

unloading in the friction measurements with separation occurring at large negative applied loads. The large hysteresis

in the friction-load relationship is attributed to a contact area hysteresis of the capillary condensate which built up

during loading and did not evaporate during the unloading regime. The magnitude of the friction force varied dramatically

between substrates and was lowest on the mica substrate and highest on the hydrophilic silica substrate, with the

hydrophobized silica and cellulose being intermediate. The adhesion due to capillary forces on cellulose was small

compared to that on the other substrates, due to the greater roughness of these surfaces.
