Strong, flexible films that allow light in but keep electromagnetic interference out

A new technique to produce relatively low-cost electromagnetic interference (EMI)-blocking composite films has been developed by a team the NYU Tandon School of Engineering, Distinguished University, Drexel University and Yale University. To fashion the films, the team employed spin-spray layer-by-layer processing (SSLbL), a method Associate Professor Andre Taylor of NYU pioneered in 2012. The system employs mounted spray heads above a spin coater that deposit sequential nanometer-thick monolayers of oppositely charged compounds on a component.
