Abstract
Thin liquid draining films of poloxamer 407 block co-polymeric surfactant solutions have been investigated using reflected laser light intensity to determine film thicknesses. Only in IM NaCl do stable thin films form. A discontinuous stepwise thinning has been found in these systems with metastable film thicknesses of, for example, 80nm and 58nm forming prior to forming a final stable film thickness of 28nm.
