论文摘要
三叶相位平衡中界面之间的二面接触角必须是整体热力学场的连续函数。我们提出的这一普遍论点预测了相图中的无障碍,即使对于短期力量,也挑战了“关键点润湿”的共同信念。通过精确解的平均场两密度功能理论的精确解,三相智力点(TCP)的三相均衡理论提供了证明。在TCP的微小附近发现了完全润湿。远离它,即使接近关键端点,也没有发生无障碍,也没有进行润湿过渡。远离TCP,可能会出现润湿阶段的润湿阶段。这些发现揭示了迄今无法解释的实验,这些实验是在三元水油 - 非国产分子的两亲性混合物上,随着一个接近两个临界端点之一,无障碍继续存在。
The dihedral contact angles between interfaces in three-fluid-phase equilibria must be continuous functions of the bulk thermodynamic fields. This general argument, which we propose, predicts a nonwetting gap in the phase diagram, challenging the common belief in "critical-point wetting", even for short-range forces. A demonstration is provided by exact solution of a mean-field two-density functional theory for three-phase equilibria near a tricritical point (TCP). Complete wetting is found in a tiny vicinity of the TCP. Away from it, nonwetting prevails and no wetting transition takes place, not even when a critical endpoint is approached. Far from the TCP, reentrant wetting may occur, with a different wetting phase. These findings shed light on hitherto unexplained experiments on ternary water-oil-nonionic amphiphile mixtures in which nonwetting continues to exist as one approaches either one of the two critical endpoints.
