By using these electrolytes, leakage problems will be eliminated due to its high viscosity. Moreover, such merits enable these electrolytes to be integrated with flexible substrates. The anodically coloring material Prussian blue (PB) and the cathodically coloring material poly(butylviologen) (PBV) will be utilized to obtain a complementary ECD for their desirable electrochromic properties. In terms of the electrolyte, poly(methyl 2-methylpropenoate) (PMMA) will be used because of its high ionic conductivity, and high transparency. The sacrifice in the transmittance change can therefore be minimized. Furthermore, the plasticizer propylene carbonate (PC) also exhibits high transparency while rendering low volatility. If the ratio between PMMA and PC was optimized, ideal electrochromic performance may be expected. On top of this, the solid-type electrolyte succinonitrile (SN) will also be incorporated since SN reveals high melting point, high transparency and high ionic conductivity. We expected that ECDs utilize SN can totally eliminate the leakage problem while giving significant optical contrast. Nevertheless, crystallization of SN tends to render the opaque grain boundaries that hugely sacrifice the transparency of the electrolyte. To attenuate the crystallization, certain amount of SiO2 nanoparticles will be blended with SN. This allows the proposed ECD exhibiting significant optical contrast.電致色變普魯士藍聚紫精膠態電解液electrochromicPrussian bluePoly(butylviologen)gel electrolyte
