Semipermeable membranes that transport only water while blocking solute flow were discovered by Nollet 200 years ago. They are relatively common in biological systems. For example, frog skin is often used as a semipermeable membrane. Synthetic membranes such as cellophane and membranes made with polyvinyl alcohol, polyurethane, and polytrifluorochloroethylene selectively transmit water. Their ability to transport water is quantified with their ultrafiltration coefficient, the proportionality constant that relates the concentration gradient to the net water flux through the membrane. The reflection coefficient measures the relative selectivity of the membrane for water and solute. A reflection coefficient of one represents the ideal semipermeable membrane where all solute is rejected and only water flows through the membrane. A reflection coefficient of zero signifies a membrane with pores that permit the flow of both solvent and solute with equal facility, i.e., the solution flows through the membrane.
