Abstract

Изобретение относится к способу изготовления полиамидных нановолокон в результате электроформования, который представляет собой способ многосоплового электроформования при использовании многосоплового устройства или бессопловое электроформование при использовании бессоплового устройства, включающему стадии, на которых прикладывают высокое напряжение, полимерный раствор, содержащий полимер и растворитель, подают в многосопловое устройство или бессопловое устройство и преобразуют под действием высокого напряжения в заряженные потоки струй, потоки струй осаждаются на подложке или захватываются коллектором, и полимер в потоках струй затвердевает, образуя в результате нановолокна, причем полимер содержит полукристаллический полиамид, характеризующийся соотношением C/N, равным, самое большее, 5,5, и среднемассовой молекулярной массой (Mw), равной, самое большее, 35000. Изобретение также относится к полиамидным нановолокнам, изготовленным по способу электроформования, а также к продуктам, изготовленным из них, и их применению.
