Abstract

The effect of inorganic salts and CuO nanoparticles on the dynamic viscosity of a lamellar liquid crystalline mesophase in the lecithin–avocado oil–tea tree oil–water system was studied using rotational viscometry in a range of shear rates from 0.01 to 1.0 s^–1. It was found that the viscosity of liquid crystals increased by a factor of 1.2–6.25 upon the introduction of aqueous solutions of NaCl, CaCl₂, and CuCl₂ with a concentration of 0.1 mol/L or higher. The introduction of spherically shaped CuO nanoparticles with a size of 92 ± 3 nm at a concentration of 0.3 wt % increased the viscosity by a factor of 1.3.

无机盐和纳米氧化铜（II）颗粒对卵磷脂液晶粘度的影响

摘要在 0.01 至 1.0 s-1 的剪切速率范围内，使用旋转粘度计研究了无机盐和纳米 CuO 粒子对卵磷脂-鳄梨油-茶树油-水体系中片状液晶介相动态粘度的影响。研究发现，引入浓度为 0.1 摩尔/升或更高的 NaCl、CaCl2 和 CuCl2 水溶液后，液晶的粘度会增加 1.2-6.25 倍。在 0.3 wt % 的浓度下，引入尺寸为 92 ± 3 nm 的球形 CuO 纳米粒子会使粘度增加 1.3 倍。

期刊介绍： High Energy Chemistry publishes original articles, reviews, and short communications on molecular and supramolecular photochemistry, photobiology, radiation chemistry, plasma chemistry, chemistry of nanosized systems, chemistry of new atoms, processes and materials for optical information systems and other areas of high energy chemistry. It publishes theoretical and experimental studies in all areas of high energy chemistry, such as the interaction of high-energy particles with matter, the nature and reactivity of short-lived species induced by the action of particle and electromagnetic radiation or hot atoms on substances in their gaseous and condensed states, and chemical processes initiated in organic and inorganic systems by high-energy radiation.
