摘要:
The invention relates to a method for producing a nanofiber-based product, comprising the steps of providing a carrier material solution comprising a carrier material, and of bringing the carrier material in contact with a collector by electrospinning the carrier material solution out of a spinning device. Thereby, the collector has a first electrical polarity and the spinning device has a second electrical polarity being opposite to the first polarity. According to the invention, the carrier material essentially consists of a polymer being at least after having contacted the collector embedded in a polymer, which polymer is formed by the crosslinker. The crosslinker is a compound according to the general formula (I) wherein R 1 is a single bond between the adjacent carbon atoms, or a carbohydrate chain having 1 to 10 carbon atoms and optionally bearing a hydroxy group, the carbohydrate chain being saturated, unsaturated or polyunsaturated, and wherein R 2 , R 3 , R 4 and R 5 are independently from each other a hydrogen; a carbohydrate chain having 1 to 10 carbon atoms and optionally bearing a hydroxy group, the carbohydrate chain being saturated, unsaturated or polyunsaturated; a hydroxy group; or a sulfhydryl group; with the provision that the compound bears at least two hydroxy groups, or two sulfhydryl groups, or one hydroxy group and one sulfhydryl group. The invention further relates to an according product and its use.
摘要:
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.
