Poly (diallyl dimethylammonium chloride)-graphene oxide multilayer film (PDDA/GO) was successfully fabricated onto a silicon substrate by a layer-by-layer self-assembly technology. Subsequently, PDDA/GO were thermally reduced to be PDDA/RGO in a vacuum. X-ray photoelectron spectroscopy (XPS) was carried out to investigate the formation and microstructure of multilayer samples, as well as by water contacted angle (WCA). Results indicates that the multilayer film was prepared successfully, and the surface energy of PDDA/RGO is lower than PDDA/GO. nanotribological properties was investigated by an atomic force microscopy (AFM). It was found that the frictional coefficients of PDDA/RGO is better than PDDA/GO. To investigate the micro-tribological behaviors, a ball-on-plate tribometer was adopted. Results show that the layer-by-layer self-assembled multilayer thin film possesses good frictional and anti-wear properties. Therefore, both nanoand micro friction performance of PDDA/RGO behaves better than PDDA/GO. The obtained samples make the further application to be more possible.

Phase-change erasable optical storage is based on the ability to switch a micron-sized region of a thin film between the crystalline and amorphous states using a diffraction-limited laser as a heat source. A bit of information can be represented as an amorphous spot on a crystalline background, and the two states can be optically identified by their different reflectivities. In a typical multilayer thin-film structure the active (storage) layer is sandwiched between one or more dielectric layers. The dielectric layers provide physical containment and act as a heat sink. A viable phase-change medium must be able to quench to the glassy phase after melting, and this requires proper tailoring of the thermal properties of the multilayer film. The present research studies one particular multilayer structure and shows the effect of an additional aluminum layer on the glass-forming ability.
