The invention relates to a method for producing a sheet material, comprising the steps of providing a carrier material solution (11) comprising a carrier material, and depositing the carrier material onto a collector (22) by electrospinning the carrier material solution (11) out of a spinning device (1), the collector (22) having a first electrical polarity (-) and the spinning device (1) having a second electrical polarity (+) being opposite to the first polarity (-). According to the invention, the collector (22) comprises at least one differential section (25), 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 s device for carrying out said method and a sheet material which can be produced by said method.
