Summary

The two dimensional compression technique ofDoroszkowski et al. has been used to study the steric repulsion force for a monolayer of poly(vinyl pyrrolidone) stabilized polystyrene latex particles spread at the Air/2M sodium chloride solution interface. Repulsion forces were first detected at a particle separation of 150 nm with a dramatic increase in repulsion at about 15 nm.

Zusammenfassung

Die sterische Abstoßung zwischen Polystyrol-Latexteilchen in einer Monoschicht wurde nach der Methode vonDoroszkowski et al. gemessen. Die Latexteilchen waren mit Polyvinylpyrrolidon stabilisiert und an der Grenzfläche einer 2M Natriumchloridlösung zur Luft gespreitet. Die Abstoßungskräfte machten sich bei einer Annäherung der Teilchen auf 150 nm zum 1. Mal bemerkbar. Sie stiegen drastisch an bei etwa 15 nm.
