Researchers from the University of Illinois at Chicago (UIC) and the Korea University developed a simple spray method to deposit high quality graphene flakes films on a range of substrates.

The method is based on a unique kinetic spray deposition system developed in Korea that was originally used to spray materials other than graphene. Together, the researchers adapted this method to graphene and they found that it dispersed evenly and it reduces the tendency of the graphene flakes to aggregate.

The researchers were also pleased to discover that using this method, defects inherent in the graphene flakes actually disappeared. This means that the resulting films were of very high quality.
