Interfacial adhesion refers to the strength of the bond at the interface between two materials, which is crucial for the performance and durability of composite materials and coatings. It is influenced by factors such as surface energy, roughness, chemical bonding, and the presence of contaminants or moisture at the interface.

performance and durability

Composite materials are engineered from two or more constituent materials with significantly different physical or chemical properties, which remain distinct within the finished structure. They are designed to achieve superior performance characteristics such as increased strength, reduced weight, or enhanced durability compared to traditional materials.

Coatings are thin layers applied to surfaces to enhance properties such as durability, appearance, or corrosion resistance, and are crucial in various industries including automotive, aerospace, and construction. They can be made from a variety of materials, including polymers, metals, and ceramics, and are applied using techniques like spraying, dipping, or electroplating.

Surface energy is a measure of the disruption of molecular bonds that occurs when a surface is created, and it plays a crucial role in phenomena such as wetting, adhesion, and surface tension. It is a critical parameter in material science, influencing the behavior of liquids and solids at interfaces and impacting processes like coating, painting, and the formation of droplets.

Chemical bonding is the process by which atoms combine to form molecules and compounds, driven by the attainment of a more stable electronic configuration. The main types of chemical bonds are ionic, covalent, and metallic, each involving different mechanisms of electron sharing or transfer.
