Flexible Air Breathable Electroluminescent Device Based on Electrospinning Process

Alternative current electroluminescent device with excellent air permeability were fabricated by a facile electrospinning method, and the optimal fabrication conditions of the device substrate and light-emitting layer, such as voltage, acceptance distance, concentration, and propulsion rate, were determined. The microscopic morphology, luminance and air permeability of the samples were explored and analyzed. The characterization results show that the flexible alternative current electroluminescent device fabricated by electrospinning method exhibits excellent mechanical properties and high air permeability. The device can reach 55.74 cd/m 2 at a voltage of 130 V and a frequency of 3 kHz, and the air permeability can reach 5.81 g/(h·m 2 ). It is discussed that its excellent breathability is attributed to the overall microns fabric structure. On the basis of these results, we believe our electrospinningac process will accelerate development of more comfortable electroluminescent devices with the flexibility required for real-world applications.
