Fluid coating from a polymer solution
New experiments on coating of a wire with aqueous poly(ethylene oxide) solutions are reported. If these experiments are compared with coating with a pure Liquid of the same physical characteristics, a strong thickening of the liquid layer is observed. This effect is described by considering the normal stresses, which allows us to obtain an analytical expression for the coated thickness in good agreement with the data.
