ABSTRACT:
A variable density fluid is provided comprising a multiplicity of polymer micro-particles or polymer microfilaments added to a suspending liquid. By varying the density, shape, size, and material of construction of the added micro-particles or microfilaments, the physical properties of the composite liquid suspension, such as density, viscosity and compressibility, are controllable. In one specific embodiment, the polymer micro-particles can be used to selectively remove a liquid from a mixture of liquids, such as oil from sea water for example.
