simple and inexpensive solution process has been developed to construct a silver film with enhanced adhesion by electroless plating for solar reflector applications. X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), atomic force microscopy (AFM) and field emission scanning electron microscopy (FE-SEM) were employed to characterize the surfaces. This reinforced adhesion is due to chemical covalent bonds between silver and substrate atoms. Silver maintains its unique conductivity even as a film on the ABS surface as demonstrated by four-point probe measurement. Moreover, UV/VIS/NIR spectrometer data confirms high reflectance of the Ag films in the infrared region indicating potential application for solar coatings. The method presented a convenient, compatible, and easily scalable manufacturing process with higher efficiency, which is of significant value for industrial fabrication of silver films and could have a promising future in concentrating solar systems.
