Influence of Added Surfactants on the Rheology and Surface

Primary surface measurement reported Surface tension of polymer and surfactant–polymer solutions was measured as a function of surfactant concentration at room temperature. Client Citation Analysis Surface tension of polymer and surfactant–polymer solutions was measured as a function of surfactant concentration at room temperature. The paper attributes surface-tension measurements to a “pendant drop tensiometer (Droplet Lab, Markham, ON, Canada),” using smartphone imaging and Young–Laplace...
