Abstract

ABSTRACT Three mesogenic compounds: n-cyano-3-fluorophenyl 4-butylbenzoates (n = 4,6,8), abbreviated 4CFPB, 6CFPB, and 8CFPB contained in mesoporous Anodic Aluminium Oxide (AAO) membranes were subjected to Small Angle Neutron Scattering measurements with the aim to test the feasibility of SANS experiment as a means of detecting a boundary layer and estimating its thickness. This proved successful for 4CFB and 6CFPB in 18 nm pores, and indicative in 35 nm pores. The thickness of the boundary layer was estimated by core-shell SANS models at ca. 23–26 Å (2.3–2.6 nm).

n-氰基-3-氟苯基-4-丁基苯甲酸酯（n = 4，6，8）中孔AAO膜中的液晶。可行性研究

摘要采用小角中子散射法对介孔阳极氧化铝(AAO)膜中含有的3种介孔化合物n-氰基-3-氟苯基- 4-丁基苯甲酸酯(n = 4,6,8)、简称4CFPB、6CFPB和8CFPB进行了测量，目的是验证用SANS实验检测边界层和估计边界层厚度的可行性。结果表明，4CFB和6CFPB在18 nm的孔隙中取得了成功，在35 nm的孔隙中也取得了成功。通过核壳SANS模型估计边界层的厚度约为23-26 Å (2.3-2.6 nm)。

期刊介绍： Phase Transitions is the only journal devoted exclusively to this important subject. It provides a focus for papers on most aspects of phase transitions in condensed matter. Although emphasis is placed primarily on experimental work, theoretical papers are welcome if they have some bearing on experimental results. The areas of interest include: -structural phase transitions (ferroelectric, ferroelastic, multiferroic, order-disorder, Jahn-Teller, etc.) under a range of external parameters (temperature, pressure, strain, electric/magnetic fields, etc.) -geophysical phase transitions -metal-insulator phase transitions -superconducting and superfluid transitions -magnetic phase transitions -critical phenomena and physical properties at phase transitions -liquid crystals -technological applications of phase transitions -quantum phase transitions Phase Transitions publishes both research papers and invited articles devoted to special topics. Major review papers are particularly welcome. A further emphasis of the journal is the publication of a selected number of small workshops, which are at the forefront of their field.
