We demonstrate that chemically modified graphenes (CMGs) enhance the growth of inorganic films on inert surfaces with poor growth properties.1 First, fluorinated graphene on polyethylene enabled the dense and homogeneous deposition of cadmium sulfide (CdS) film grown via chemical bath deposition (CBD). We show the coverage of CdS film can be controlled by the degree of fluorination from less than 20% to complete coverage of the film. Our approach is also applicable to other technologically important materials such as ZnO. Secondly, we show that an electron beam SF6 plasma can pattern fluorine onto a graphene/PE sample to selectively grow CdS films on the fluorinated region. Lastly, we demonstrate CMGs on glass enhances the growth of lead sulfide (PbS) film grown via CBD. Therefore, CMG coatings can be utilized as a universal layer to tailor the surface properties of substrates and control the growth of inorganic thin films.
