Spreading of trisiloxanes over thin aqueous layers

Water-bath assisted convective assembly of aligned silver nanowire films for transparent electrodes

“…Generally, when a small droplet of an aqueous surfactant is slowly dropped on a thin water surface, the gravitational forces can be neglected and the droplet of the aqueous surfactant will not dissolve into the water immediately but spread first due to the Marangoni effect. 41 In our 10 experiments, the same phenomenon was observed when droping isopropanol on the water surface. For without water-bath, when dropping AgNW isopropanol dispersion on the water surface, AgNWs quikly sedimentated into the water due to the gravity and the weak nature convective flow though they had the trend to 15 spread (Fig.…”

Surface forces action in a vicinity of three phase contact line and other current problems in kinetics of wetting and spreading

“…The identical experimental arrangement can be used for investigation of behaviour of trisiloxane solutions ("superspreaders") [55]. It is shown that the time evolution of the moving front in the case of trisiloxane solutions differs substantially from that of regular surfactants.…”

“…19). The time evolution of the radius of the moving front can be monitored and information on the properties of surfactants can be extracted [52][53][54][55]. In [53] surfactants of different solubility were used at concentrations above CMC.…”

Spreading of surfactant solutions over thin aqueous layers at low concentrations: Influence of solubility

“…The latter allows extracting properties of surfactants on a liquid-air interface as described in [3,4]. The same method was used for an investigation of properties of trisiloxane solutions [5].…”
