纳米粒子(NP)在气液界面上的线张力可以通过考察NP溶液表面张力随体NP浓度的变化来确定。在这本出版物中，研究了从正十八烷到正十八烷的同系液体的线张力随液体溶剂的变化。通过考察纳米粒子在空气-十八烷表面的线张力随NP尺寸的变化，研究了有限尺寸的线张力效应。用线张力的界面位移模型可以定性地解释线张力随溶剂和NP尺寸的变化。
The line tension for a nanoparticle (NP) at the air–liquid surface can be determined by examining the variation in NP solution surface tension with bulk NP concentration. In this publication the variation in line tension with liquid solvent is examined for the homologous series of liquids fromn-decane through ton-octadecane. Finite-size line tension effects are also studied by examining the variation in line tension with NP size for NPs at the air–octadecane surface. Both the line tension variation with solvent and NP size can be qualitatively explained using an interface displacement model for the line tension.
