    根据权威词典的定义和相关解释,"interfacial energy"(界面能)是指两种不同物质接触界面处的能量状态。其核心概念可拆解为:

    1. 词源解析

      • "interfacial" 由 inter(之间)和 facial(表面)组成,表示"界面上的"或"两表面间的"
      • "energy" 在物理化学中特指系统储存或释放的能量
    2. 科学定义
      指在两种不相溶物质(如液体-气体、固体-液体等)的交界面上,由于分子间作用力差异产生的能量。这种能量会驱动界面形态变化,例如液滴的收缩或铺展现象。

    3. 相关参数
      常与"界面张力"(interfacial tension)相关联,两者在数值上等同,单位均为焦耳/平方米(J/m²)。界面能越高,物质间的混溶性越差。

    4. 应用领域
      在材料科学中影响润湿性、吸附性;在生物膜研究中决定细胞膜稳定性;在工业领域与乳化、涂层技术等密切相关。

    如需更专业的量化分析,建议参考《表面物理化学》等教材,其中包含界面能的热力学计算公式: $$ ΔG = γ cdot ΔA $$ 式中γ为界面能,ΔA为界面面积变化。

    Interfacial energy is the energy required to create a boundary between two different materials or phases, such as the surface of a liquid and the air above it. It is also known as surface energy or surface tension.

    Interfacial energy is an important concept in materials science and engineering, as it determines the behavior of materials at interfaces or boundaries. For example, the interfacial energy between two solids can affect the adhesion or cohesion between them, while the interfacial energy between a liquid and a solid can affect wetting and spreading.

    例句

    用法

    Interfacial energy is often used in the study and characterization of materials, such as in the measurement of contact angles or in the analysis of surface tension. It is also used in the design and development of new materials, such as coatings or composites, where the interfacial energy between different materials can be manipulated to achieve desired properties.

    解释

    Interfacial energy is a measure of the energy required to create or maintain an interface between two different materials or phases. It is a result of the differences in the chemical or physical properties of the materials at the interface, such as the composition, structure, or bonding. Interfacial energy can be calculated or estimated using various experimental or theoretical methods.
