Once the surface tension of neat polymers was calculated, the interfacial tension between PTT and PA6 was determined as shown in Table 2.
where [theta] is the Young contact angle, [[gamma].sub.lg] is the liquid-gas surface tension, [[gamma].sub.sg] is the solid-gas surface tension, and [[gamma].sub.sl] is the solid-liquid interfacial tension. It should be pointed out that (1) is only applicable to thermodynamically meaningful contact angles [18].
Interfacial tension is 0.001 mN/m, initial wetting angle is 47[degrees], quantity of flow is 2e - 10 [m.sup.3]/s, viscosity ratio is 0.25, Ca is 1.2, Re is 2.5e - 6, and We is 0.4.
Generally, the interfacial affinity between polymer components and inorganic fillers and the preferential localization of the fillers in the composites can be predicted by interfacial tensions between polymers and additives.
NPs can have a strong effect on the interfacial tension. Silicon oxide NPs have been extensively used in EOR [83].

Therefore, this study was taken to characterise the effects of SDS, Tween-20, NaOct and CTAB on the surface and interfacial tensions and reduced viscosities of aqueous starch solutions and to get better understanding of structure/property relations and help to determine feasibility of certain applications i.e., by the ternary phase diagram, interfacial surface tension and viscosity measurement.
(2) Zwitterionic surfactant (BS-12) can reduce dodecanoic-water interfacial tension to about 0.3 mN/m.
Where (gamma) sd and (gamma) sc are the interfacial tensions of the respective boundary of solid/disperse phase and solid/continuous phases, and (gamma) cd is the interfacial tension between the two liquid phases.
It is also known that the attainment of three phases in mixtures of oil, water and an ionic surfactant produces low and ultralow values of the interfacial tension between the immiscible phases (Salager et al., 1979; Bourrel et al., 1980).
