Long-Range Order and Interactions of Macroscopic Objects in Polar Liquids

Abstract

We develop a phenomenological vector model of polar liquids capable to describe aqueous interactions of macroscopic bodies. It is shown that a strong, long-range and orientationally dependent interaction between macroscopic objects appears as a result of competition between short-range (hydrogen bonding) and the long-range dipole-dipole interactions of the solvent molecules. Spontaneous polarization of molecular dipoles next to a hydrophobic boundaries leads to formation of globally ordered network of hydrogen-bonded molecules with ferroelectric properties. The proposed vector model naturally describes topological excitations on the solute boundaries and can be used to explain the hydrogen bonds networks and order-disorder phase transitions in the hydration water layer.
