Abstract [en]

Electroluminescence (EL) is the property of a semiconductor material pertaining to emitting light in response to an electrical current or a strong electric field. The purpose of this paper is to develop a flexible and lightweight EL device. Thermogravimetric analysis (TGA) measurement was taken to observe the thermal degradation behavior of NinjaFlex. Poly (3, 4-ethylenedioxythiophene): poly (styrene sulfonic acid) (PEDOT:PSS) with ethylene glycol (EG) was coated onto polyester fabric where NinjaFlex was placed onto the coated fabric using three-dimensional (3D) printing and phosphor paste and BendLay filament were coated 3D-printed subsequently. Adhesion strength and flexibility of the 3D-printed NinjaFlex on textile fabrics were investigated. The TGA results of the NinjaFlex depicts that no weight loss was observed up to 150°C. Highly conductive with a surface resistance value of 8.5 ohms/sq., and uniform surface appearance of coated fabric were obtained as measured and observed by using four-probe and scanning electron microscopy (SEM), respectively at 60% PEDOT:PSS. The results of the adhesion test showed that peel strengths of 4160, 3840 N/m were recorded for polyester and cotton specimens, respectively. No weight loss was recorded following three washing cycles of NinjaFlex. The bending lengths were increased by only a factor of 0.082 and 0.577 for polyester and cotton samples at 0.1 mm thickness, respectively; which remains sufficiently flexible to be integrated into textiles. The prototype device emitted light with a 12 V alternating current (AC) power supply.
