From: Interaction of surfactants with Prunus laurocerasus leaf surfaces: time-dependent recovery of wetting contact angles depends on physico-chemical properties of surfactants

Fig. 5

Time-dependent recovery of wetting contact angles of water on Prunus leaf surfaces sprayed with CTAB (a), SDS (b) and Glucopon (c). Surfactant coverage of leaf surfaces were 1 µg cm−2. Wetting contact angle measurements were started after sprayed surfactant solution had fully dried. Wetting contact angles on Prunus leaves treated with deionized water represent the control (dotted black lines). With SDS and Glucopon there was no regeneration of wetting contact angles. With CTAB there was a partial regeneration of the wetting contact angles within the first 8 h. Data points represent means with standard deviations (n = 15)
