Substrate surface modification involves altering the surface properties of a material to enhance its performance or compatibility in various applications, such as adhesion, corrosion resistance, or biofunctionality. This is achieved through physical, chemical, or biological methods that can change surface energy, roughness, or chemical composition without affecting the bulk properties of the substrate.

Adhesion is the tendency of dissimilar particles or surfaces to cling to one another due to intermolecular forces. It plays a critical role in various natural and industrial processes, such as the sticking of water droplets to leaves and the bonding of materials in construction and manufacturing.

Adhesion

Corrosion resistance refers to the ability of a material, often a metal, to withstand damage caused by oxidization or other chemical reactions with its environment. It is a critical property for materials used in harsh environments to ensure longevity and structural integrity.

Surface roughness is a measure of the texture of a surface, characterized by the vertical deviations of a real surface from its ideal form. It is crucial in determining the performance and longevity of mechanical components, affecting friction, wear, and the ability to form a tight seal.

Surface Roughness

Chemical composition refers to the identity and relative number of the elements that make up any particular compound or substance. Understanding chemical composition is crucial for determining the properties and potential reactions of a substance, which is essential in fields such as chemistry, materials science, and pharmacology.
