Hydrophilic Resin Surface Coatings for Hydrophobic Polyester Surfaces

Difficulty is encountered in electroplating and electroless plating polyester materials, such as polyethylene terephthalate, due to their hydrophobic character.

This shortcoming is overcome by coating the surface with hydrophilic materials. One such group of materials consists of resins which are polar in nature. Polar prime coatings upon hydrophobic surfaces make it possible to present a hydrophilic surface to the plating solution. Additionally polar coatings attract ions, present in a plating solution, to the reacting surface.

Strong polarity is associated with polypeptide resins such as gellatin, glue, colagen and synthetic polypeptides. Other polar resins of a similar nature include polyamides, such as nylon, and polyimides.

These enumerated resins and many others of a similar nature can be used to impart hydrophilic character to the surface of an otherwise hydrophobic material. Thus, the material's susceptibility to plating in both a quantitative and qualitative manner is improved.
