For the first time, multilayer graphene films on quartz glass were obtained by carbonization of the Langmuir-Blodgett films of polyimide. On the Raman spectra of the carbonized polyimide films, the G, D bands and a wide band in the region of 2300–3200 cm-1 were observed. Using the method of transmission microscopy, it was shown that films consist of “stacks” of layers with a interlayers distance of 0.36 nm. The surface resistance of films 5 nm thick was 1.2±0.2 kOmega, and the transmittance was 87% at lambda=550 nm. In the infrared region of the spectrum, the transmittance was 97%, and in the UV region 70-80%.
