New Film Blocks Electromagnetic Interference
This story features the research of André D. Taylor, professor of chemical and biomolecular engineering at NYU Tandon.
Researchers from New York University (NYU) Tandon School of Engineering have created a new type of composite film capable of blocking electromagnetic interference (EMI). The new technique is both low-cost and extremely effective. To construct this high-tech composite film, scientists used spin-spray layer-by-layer processing. This involves placing spray heads above a spin coaster. The heads rain down sequential, nanometer-thick monolayers of oppositely-charged compounds. The end result is a high-quality film that can be attached to any component. This method has the added benefit of being far more time-efficient than previous methods for making film.
