| Summary: | 博士 === 國立雲林科技大學 === 化學工程與材料工程系 === 105 === In this study, dithienylpyrrole-, carbazole-, tris(biphenyl-4-yl)amine-based electrochromic materials, and their copolymers were investigated using electrochemical analyzer and UV-Visible spectrophotometer.
PMPS film showed higher ∆Tmax (54.47% at 940 nm) than those of the PMPO and PANIL films in an ionic liquid solution. Electrochromic devices (ECDs) employ PMPS, PMPO, and PANIL as anodic layers and poly(3,4-(2,2-diethypropylenedioxy)thiophene)(PProDOT-Et2) as a cathodic layer were constructed. PMPO/PProDOT-Et2 ECD showed the highest ∆Tmax (41.13%) and coloration efficiency (674.67 cm2C-1) at 626 nm.
In the second part, P(MPS-co-TTPA), P(MPO-co-TTPA), and P(ANIL-co-TTPA) were copolymerized electrochemically. P(MPS-co-TTPA), P(MPO-co-TTPA), and P(ANIL-co-TTPA) showed higher optical contrast and shorter switch time than those of PMPS, PMPO, and PANIL, respectively.
In the third part, PDTC, PS2CBP, PCEC, and PTTBA were electrosynthesized using electrochemical polymerization. The PDTC film showed higher optical contrast (ΔTmax =58.79 % at 578 nm and ΔTmax =66.04 % at 856 nm) than those of PS2CBP, PCEC, and PTTBA films in an ionic liquid solution. PCEC/PProDOT-Et2 ECD showed higher optical contrast (ΔTmax=38.25% ) than that of PDTC/PProDOT-Et2 ECD. PTTBA/PProDOT-Et2 ECD showed high optical contrast(ΔTmax= 54.47%) and coloration efficiency (563.81 cm2C-1).
In the fourth part, P(DTC-co-DTP)/PProDOT-Et2 ECD showed about six type colors. P(S2CBP-co-TTBA)/ PProDOT-Et2 ECD exhibited higher optical contrast (ΔTmax= 45.77%) than that of PS2CBP/PProDOT-Et2 ECD (ΔTmax= 34.45%), whereas P(CEC-co-BSe)/PProDOT-Et2 ECD dispalyed lower optical contrast (ΔTmax= 22.75%) than that of PCEC/PProDOT-Et2 ECD (ΔTmax= 38.25%).
