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.

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）。
