In this study, we have prepared an electrochromic (EC) ink composed of WO3 nanoparticles and poly (3,4-ethylenedioxythiophene):poly (styrene sulfonate) (PEDOT:PSS). The ink formulation can be processed through inkjet-printing or spray coating to deposit high-quality EC layers. The PEDOT:PSS acts as an conductive binder to connect the WO3 nanoparticles leading to reduced impedance and better electrochemical properties. The WO3/PEDOT:PSS (PH1000) exhibits an optical modulation of 54.1%, a response time of 1.1 s, and a coloration efficiency of 83.87 cm2/C. A hybrid type electrochromic device (ECD) incorporated with WO3/PEDOT:PSS with excellent durability has been fabricated. The performance of WO3/PEDOT:PSS based ECD for sun shielding property is also evaluated. The ECD can efficiently block the sunlight and reduce solar heat gain. As a result, the indoor temperature can be modulated from 32.7 °C (bleached state) to 29.4 °C (darken state) under illumination.

喷墨印刷电致变色窗的WO 3 / PEDOT:PSS复合材料的简便制备及其隔热性能

在这项研究中,我们准备了由WO 3纳米粒子和聚(3,4-乙撑二氧噻吩):聚(苯乙烯磺酸盐)(PEDOT:PSS)组成的电致变色(EC)墨水。可以通过喷墨印刷或喷涂来处理油墨配方,以沉积高质量的EC层。PEDOT:PSS用作连接WO 3纳米粒子的导电粘合剂,从而降低了阻抗并提高了电化学性能。WO 3 / PEDOT:PSS(PH100​​0)的光学调制为54.1%,响应时间为1.1 s,着色效率为83.87 cm 2 / C。已经制造出结合有具有优异耐久性的WO 3 / PEDOT:PSS的混合型电致变色器件(ECD)。WO 3的性能/ PEDOT:基于PSS的ECD的防晒性能也得到了评估。ECD可以有效地阻挡阳光并减少太阳热能的吸收。结果,在照明条件下,室内温度可以从32.7°C(漂白状态)调节到29.4°C(变暗状态)。
