Abstract

The invention discloses electrostatic spinning equipment and a method thereof for preparing one-dimensional ordered PAMPS (2-Acrylamide-2-methylpro panesulfonic acid) / PNIPAAm (Poly(N-Isoprolacrylamide) micro-nanofibers, relating to electrostatic spinning equipment and a method thereof for preparing one-dimensional ordered micro-nanofibers. The invention solves the problem that the traditional electrostatic spinning equipment is unavailable for the production of large-area one-dimensional ordered micro-nanofibers. The electrostatic spinning equipment comprises a high voltage source, a receiving device, a boost pump, an injection syringe and a nozzle, wherein the receiving device is composed of an aluminum foil and a quartz glass receiving sheet arranged on an aluminum foil receiving surface in parallel, and the aluminum foil surface is vertical to the spinning direction of the nozzle. The method comprises the following steps of: preparing electrostatic spinning liquid of which the polymer mass concentration is 7-14%; injecting the electrostatic spinning liquid into the injection syringe; fixing the injection syringe on the boost pump; setting an electrostatic spinning parameter; and starting the equipment. In the equipment, the quartz glass sheet serves as the receiving sheet, the electric field distribution of an aluminum foil receiving plate is changed, and the large-area one-dimensional ordered micro-nanofibers are prepared. The one-dimensional ordered PAMPS / PNIPAAm micro-nanofibers are obtained by spinning, with diameters evenly distributed.
