Description

19 Calculate and construct a potential curve of interaction of spherical particles with diameters of 100 nm, if the potential of the diffuse layer is φ = 1 • 10-2 B; The Hamaker constant A = 1.25 • 10-25 J; the parameter χ = 1 · 108 m-1; ε = 80.1; ε0 = 8.85 10-12 F / m; T = 293 K. The interaction energy should be calculated for distances between the particle surfaces h = 5, 10, 20, 30, 50 nm.
