Abstract
It is provided that a polymer film; a preparation method of the polymer film; and a laminated body used the polymer film. The polymer film is suitable for use in producing a laminate body which comprises a support and a polymer film, and is reduced in foreign-matter trapping and which can be used for supplying film devices using conventional apparatuses for glass substrates or silicon substrates. The polymer film coated with the layer of silane coupling agent, which is suitable for producing a laminate that comprises a support and a polymer film, comprises a silane coupling agent layer formed on at least one surface of the polymer film, wherein the silane coupling agent layer has a three-dimensional surface roughness (Sa) of 5.0 nm or less. The method of efficient for producing the polymer film coated with the above layer is the method for producing without using a vacuum.
