为了在纳米多孔聚乙烯（nanoPE）基底上制备红外热致变色VO2纳米颗粒薄膜，开发了可喷墨打印的VO2油墨。通过扫描电子显微镜（SEM）和原子力显微镜（AFM）的表面形貌和粗糙度的印刷薄膜进行了研究。所获得的薄膜表现出优异的红外光学性能与大的红外光学调制（32.4%，在20 μ m波长）。此外，喷墨打印的560 cm（2）的大面积VO2纳米颗粒薄膜具有良好的均匀性，薄膜上40个区域的红外透射率差异在0.3%以内。这些研究结果有助于推动该材料在智能伪装、光开关等光电器件中的应用。
Inkjet-printable VO2 inks were developed for fabrication of infrared thermochromic VO2 nanoparticle films on the nanoporous polyethylene (nanoPE) substrates. The surface morphology and roughness of the printed films were investigated via scanning electronic microscopy (SEM) and atomic force microscopy (AFM). The obtained films demonstrated excellent infrared optical properties with large infrared optical modulation (32.4% at 20 mu m wavelength). Moreover, the inkjet printed large area VO2 nanoparticle films of 560 cm(2) had good uniformity, which the difference in infrared transmittance of the 40 regions on the film was within 0.3%. These promising results help to promote the applications of this material in optoelectronic devices such as intelligent camouflage and optical switches.
