Abstract

An investigation of the time-dependent behavior of the normal forces between two smooth mica surfaces immersed in salt-free water was presented, using a surface force balance (SFB). An equilibrium surface-charge density σ = σ₀ was indicated by a long-ranged repulsion on initial approach to adhesive contact. The results showed that subsequent force measurements at times τ following separation of the surfaces revealed drop in σ, followed by contact and separation, but then relaxed back to σ₀ with a characteristic time τ_r = 11 ± 2 minutes.
