Effective interactions between a pair of nanoparticles
Original language description
We investigate the effective interactions between two nanoparticles (or colloids) immersed in a solvent exhibiting two-phase separation. Using a non-local density functional theory, we determine the dependence of the effective potential on the separationof the nanoparticles when the solvent is near bulk two-phase coexistence. If identical nanoparticles preferentially adsorbing phase alpha are inserted into phase beta, thick wetting layers of the preferable phase alpha develop at their surfaces. At someparticular separation h(b) of the nanoparticles, the wetting layers connect to form a single bridge, and the induced effective potential becomes strongly attractive for all distances h < h(b). The bridging is a first order capillary condensation like transition for all radii of the nanoparticles greater than the critical radius R-c, the value of which was estimated to be approximately R-c approximate to 20 sigma for a temperature T/T-c approximate to 0.9, where sigma is the size of the
