Abstract: A method for producing a sheet material is disclosed, comprising the steps of providing a carrier material solution comprising a carrier material, and depositing the carrier material onto a collector by electrospinning the carrier material solution out of a spinning device, the collector having a first electrical polarity and the spinning device having a second electrical polarity being opposite to the first polarity. The collector comprises at least one differential section, the electrical polarity of which is adjusted during deposition of the carrier material in such a manner that it either resembles the electrical polarity of the remaining sections of the collector or differs from it. The invention further relates to a device for carrying out said method and a sheet material which can be produced by said method.
