From Colloidal Particles at Liquid Interfaces
Chapter 1: Colloidal Particles at Liquid Interfaces An Introduction
- Figure 1.1: Schematic of (a) homogeneous, (b) heterogeneous or amphiphilic (Janus) colloidal particles and (c) a surfactant molecule.
- Figure 1.2: Heavy solid spherical particle with radius r and contact angle ? in equilibrium at the oil water interface levelled at z = 0 far from the particle. The three-phase contact line with radius r c is depressed at depth z c below the zero level. Other symbols are defined in the text.
- Figure 1.3: Small solid spherical particle with radius r and contact angle ? (a) attached to a planar oil water interface in its equilibrium state 1 and (b) after its detachment into oil in state 2 .
- Figure 1.4: Possible interfacial profile around an ellipsoidal particle with contact angle 45 , aspect ratio a/b = 4 and both short axes equal to 2.52 ?m oriented with its long axis parallel to the fluid interface. Taken from Ref. [30]; with permission of the American Physical Society.
- Figure 1.5: Free energy of detachment of a spherical particle into water (squares) and into oil (circles) calculated by equations (1.15) (a) and (b) with r = 10 nm and ? ow = 50 mN m ?1 versus particle contact angle ?. The line is drawn according to equation (1.16).
- Figure 1.6: Non-spherical particles with contact angle ? = 45 attached to a planar oil water interface in the case of (a) a rod-like particle with hemispherical ends and...
