In recent years, metallization of polymers has been intensely studied due to its superior properties of both plastics and metals. Laser direct structuring (LDS) is one of the most widely used technologies to obtain metal patterns on polymer substrates. In LDS technology, different methods including injection-molding, drop casting, dip coating, and spin coating are utilized for surface preparation of polymer materials prior to laser activation process. In this study, an atomization based dual regime spray coating system is offered to prepare LDS materials. Furthermore, its advantages and limitations are discussed. The results show that the dual regime spray coating system can be potentially used to obtain uniform thin film coating with relatively less material consumption on polymer materials for laser direct writing.
