Clear visualization of the layer structure of multilayer films using low-damage sputtering with GCIB.
The functionality of films is known to be determined by factors such as material, thickness, and layer structure. In this study, we evaluated the layer structure of polyethylene-based multilayer films commonly used as food wrap. By confirming that the film is primarily composed of polyethylene using FT-IR, and employing GCIB (Ar cluster) for sputtering, we were able to clearly visualize the structure where polyethylene and nylon 6 are layered within a thickness of 10μm through depth profiling with TOF-SIMS.
