摘要

本文主要研究了不同摩尔分数的卟啉和花生酸混合单层在空气-水界面上的动态表面性质。选择卟啉固体薄膜作为研究对象，是因为它在光伏和医药领域具有很高的应用潜力。采用Langmuir- blodgett技术，在不同条件下制备了卟啉和花生酸的Langmuir单分子膜。亚相温度的升高导致卟啉单分子膜刚度的降低，加速了单分子膜的弛豫过程。选择的表面压力(4、5、15和35 mN/m)影响了浮膜的稳定性。在卟啉摩尔分数= 0.333时，单分子膜具有较高的混溶性。在表面电位数据的基础上，报道了单层膜表面相的变化。研究了用Schaeffer法在硅衬底上转移的混合体系的形貌特性。

Formation and phase behavior of porphyrin/arachidic acid mixed systems and morphology study of Langmuir-Schaefer thin films

ABSTRACT The paper is focused on the study of the dynamic surface properties of mixed monolayers of porphyrin and arachidic acid with various mole fractions at the air–water interface. The choice of porphyrin solid thin film as an object of study is explained by its high potential application in the area of photovoltaics and medicine. The Langmuir monolayers of porphyrin and arachidic acid were formed under different conditions using the Langmuir-Blodgett technique. The increase of subphase temperature led to a decrease in the rigidity of the porphyrin monolayer and leads to accelerating the relaxation process of the monolayer. The chosen surface pressure (4, 5, 15 and 35 mN/m) affected the stability of the floating monolayer. The higher miscibility of the monolayers was obtained at the mole fraction of porphyrin = 0.333. The change in the phase of monolayers surface was reported on the basis of surface potential data. The morphology properties of the mixed systems transferred on silicon substrates by Schaeffer method are studied.

期刊介绍： Providing a common forum for all soft matter scientists, Soft Materials covers theory, simulation, and experimental research in this rapidly expanding and interdisciplinary field. As soft materials are often at the heart of modern technologies, soft matter science has implications and applications in many areas ranging from biology to engineering. Unlike many journals which focus primarily on individual classes of materials or particular applications, Soft Materials draw on all physical, chemical, materials science, and biological aspects of soft matter. Featured topics include polymers, biomacromolecules, colloids, membranes, Langmuir-Blodgett films, liquid crystals, granular matter, soft interfaces, complex fluids, surfactants, gels, nanomaterials, self-organization, supramolecular science, molecular recognition, soft glasses, amphiphiles, foams, and active matter. Truly international in scope, Soft Materials contains original research, invited reviews, in-depth technical tutorials, and book reviews.
