Abstract
double-layer forces normally decay exponentially with
separation distance. Here, we present experimental evidence
of algebraically decaying double-layer interactions. We show
that algebraic interactions arise in both strongly overlapping as
well as counterion-only regimes, albeit the evidence is less
clear for the former regime. In both of these cases, the
disjoining pressure profile assumes an inverse square distance
dependence. At small separation distances, another algebraic
regime is recovered. In this regime, the pressure decays as the
inverse of separation distance.
