An oil-swollen surfactant membrane is employed to measure the effects of incorporated hydrophobically functionalized gold nanoparticles (AuNPs) on the structure and dynamics of the membranes. While maintaining an average AuNP diameter of approximately 5 nm, the membrane thickness was varied from 5 nm to 7.5 nm by changing the amount of oil in the membrane. The membranes become softer as the proportion of oil is increased, while the thickness fluctuations become slower. We attribute this to an increased fluctuation wavelength. Incorporation of AuNPs in the membrane induces membrane thinning and softening. Oil molecules surround the nanoparticles in the membrane and help their relatively homogeneous distribution. AuNPs significantly alter the membrane's structure and dynamics through thinning of the membrane, increased compressibility, and possible diffusion of AuNPs inside the membrane.

金纳米粒子掺入油溶胀的表面活性剂层状膜中的作用

使用溶胀的表面活性剂膜来测量掺入的疏水功能化金纳米颗粒（AuNPs）对膜结构和动力学的影响。在保持约5nm的平均AuNP直径的同时，通过改变膜中的油量将膜厚度从5nm改变为7.5nm。膜随着油的比例增加而变软，而厚度波动则变慢。我们将此归因于波动波长的增加。在膜中掺入AuNP会引起膜变薄和软化。油分子围绕着膜中的纳米颗粒，帮助它们相对均匀地分布。AuNPs通过使薄膜变薄，增加可压缩性来显着改变薄膜的结构和动力学，
