The conductive substance is capable to confer electrochromic properties to the material. The organic plastifiers is a liquid crystal such that in the film the mycro drops of liquid crystal are present, so that the film beyond having electrochromic properties has also electro-optical properties of PDLC type and is capable the change its transparence after electric fields application. The organic and/or inorganic conductive layers and isolating layers are depositated on it. These layers are such that the material can be used as an electrochromic material without being substained by prefabbricated supports. The film is contained between rigid or flexible transparent preformed supports, having the conductive internal surfaces.
