The production and structure of hydrophilic foil

Hydrophilic aluminum foil is a special type of aluminum foil that has been treated to have a hydrophilic (water-absorbing) surface. The production process of hydrophilic foil typically involves the following steps:

Raw foil → cleaning → coating (hydrophilic layer, corrosion-resistant layer) → drying and curing → cutting → final hydrophilic foil product.

The finished product encompasses the following structure:

  • Substrate aluminum foil: the core material is standard aluminum foil, typically made from high-quality pure aluminum and rolled into thin sheets.
  • Hydrophilic coating: hydrophilic properties are achieved by applying a specialized coating on one or both sides of the aluminum foil.
  • Surface treatment: hydrophilic coatings are usually applied through chemical or electrochemical processes to make them more attractive to water molecules.
  • Microstructure: hydrophilic treatment alters the surface of the aluminum foil, reducing its contact angle with water droplets. This means that water droplets will spread and form a thin film on the surface rather than forming droplets.
