Abstract

Способ производства нановолокон из полимерного раствора методом электростатического формования волокна в электрическом поле, созданном за счёт разности потенциалов между собирательным электродом (4) и поворотно расположенным волокнообразующим электродом (1) продолговатой формы, который частью своей окружности погружен в полимерный раствор (3), при этом за счёт вращения волокнообразующего электрода (1) полимерный раствор (3) по крайней мере частями поверхности этого электрода выносится в электрическое поле, в котором на поверхности собирательного электрода (4) формуются нановолокна, которые уносятся к собирательному электроду (4) и укладываются на поверхность подкладочного материала (5), проложенного между волокнообразующим электродом (1) и собирательным электродом (4) вблизи от собирательного электрода (4). На полимерный раствор (3) на поверхности волокнообразующего электрода (1) в месте линии пересечения поверхности волокнообразующего электрода (1) и плоскости, проведённой через ось волокнообразующего электрода (1) и перпендикулярной к плоскости подкладочного материала (5), направлено по всей длине волокнообразующего электрода (1) действие электрического поля максимальной и одинаковой напряжённости, за счёт чего достигается высокий и равномерный эффект формования волокна по всей длине волокнообразующего электрода (1). Изобретение касается также устройства для производства нановолокон из полимерного раствора методом электростатического формования волокна.A method of producing nanofibers from a polymer solution by electrostatic forming a fiber in an electric field created by the potential difference between the collecting electrode (4) and the fiber-forming elongated fiber-forming electrode (1), which is immersed in a polymer solution (3) with its circumference due to the rotation of the fiber-forming electrode (1), the polymer solution (3) is carried out by at least parts of the surface of the electrode into an electric field in which it collects on the surface The core electrode (4) forms nanofibres that are carried to the collecting electrode (4) and placed on the surface of the lining material (5) laid between the fiber-forming electrode (1) and the collecting electrode (4) near the collecting electrode (4). The polymer solution (3) on the surface of the fiber-forming electrode (1) at the intersection of the surface of the fiber-forming electrode (1) and the plane drawn through the axis of the fiber-forming electrode (1) and perpendicular to the plane of the lining material (5) is directed along the entire length of the fiber-forming electrode (1) the action of an electric field of maximum and equal intensity, due to which a high and uniform effect of fiber formation is achieved along the entire length of the fiber-forming electrode (1). The invention also concerns a device for the production of nanofibers from a polymer solution by electrostatic fiber spinning.
