Line tension and its influence on droplets and particles at surfaces

Entropy Contribution to the Line Tension: Insights from Polymer Physics, Water String Theory and the Three-Phase Tension

“…It is noteworthy, that the impact of the entropic term into the line tension is necessarily positive (the sign of the line tension remains debatable [6,7,11,5]). It is also recognized that the value of remains considerable for (values of have been reported [9].…”

“…Experimental values of a line tension  in the range of N were reported [6][7][8][9][10][11]. Very few methods allowing experimental measurement of line tension were developed [9][10][11][12][13][14] -9 N, and that it is positive for acute and negative for obtuse Young angles [15][16].…”

“…Very few methods allowing experimental measurement of line tension were developed [9][10][11][12][13][14] -9 N, and that it is positive for acute and negative for obtuse Young angles [15][16]. However, researchers reported negative values of the line tension for hydrophilic surfaces [14].…”

Effect of line tension on axisymmetric nanoscale capillary bridges at the liquid-vapor equilibrium

“…We also consider the bridge only at the liquid-vapor equilibrium because the liquid-vapor meniscus is exactly given by the catenary [21,29,44], and we can avoid numerical uncertainty of the shape of meniscus due to the numerical integration of differential equations. The microscopic effects for the nanoscale bridges will be taken into account by considering the effective line tension [34,35,[45][46][47][48][49]. This strategy has been already adopted by Dutka and Napiórkowski [50,51], and Aveyard et al [40] who showed that the effective line tension can include the effect of disjoining pressure.…”

Organoelement Coatings on Glass as Precursors for Biochip Technologies

“…A wide range of the grafting polymer chains allows to choose the desired surface characteristics of the phase separation and to obtain new hybrid materials. Grafted compounds determine surface chemical and physical properties at the interface of phases while the nature of the substrate determines the physical properties of the material as a whole …”
