Abstract: The prepared multi-layer compounded spring nano-films were characterized by using x-ray photoelectron spectroscope（XPS） and laser Raman scattering spectroscope,and the film topography and structure were obtained.Experimental results indicate that there are two stages in the process of formation of the spring film: the quantity increasing and the growing up of "island".Simultaneity,increasing the reaction time to 50 minute and temperature to 220℃ help to form still uniform and compact multi-layer nano-film,furthermore surfactants groups of coupling agent A187 lead to uniform SEBS film.
