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

Fig. 1

Time-dependent recovery of wetting contact angles of water on Prunus leaf surfaces after spraying with non-ionic alcohol ethoxylates. Wetting contact angles were measured after drying of the sprayed surfactant solutions. Leaf surface coverages of C12E2 (a), C12E4 (b), C12E6 (c), C12E8 (d) and Brij L4 (e) were 1 µg cm−2. Wetting contact angles on Prunus leaves previously treated with deionized water represent the control (dotted black lines). Rates of recovery were calculated from regression lines fitted to the time interval between 0 and 6 h. Data points represent means with standard deviations (n = 15)
