【摘要】：導電聚合物的發(fā)現(xiàn)開辟了此類材料新的研究與應用領域,聚3,4-乙撐二氧噻吩/聚苯乙烯磺酸鹽(PEDOT:PSS)因其導電性能好、易成膜、環(huán)境穩(wěn)定性好、透光性好、無污染等優(yōu)點成為導電聚合物領域的研究熱點。本文主要針對PEDOT:PSS導電聚合物薄膜的制備及摻雜改性展開研究,主要內容涉及以下幾個方面:(1)通過正交實驗研究靜電紡絲工藝參數(shù)對PEDOT:PSS薄膜光學性能的影響,得出了最佳紡絲工藝參數(shù):電壓17 k V、接收距離13 cm、針頭型號8號、紡絲時間14 min。并利用ANSYS模擬軟件模擬了電場分布。研究了熱處理溫度對薄膜導電性能的影響,得出最佳熱處理溫度為120℃。在最佳紡絲工藝參數(shù)和最佳熱處理溫度下,利用靜電紡絲裝置成功制備了PEDOT:PSS薄膜。其透光率為89.37%,方阻為49Ω/□的。SEM測試結果表明PEDOT:PSS薄膜表面致密光滑,無孔狀結構和團聚顆粒。(2)選用多壁碳納米管(MWCNTs)對PEDOT:PSS薄膜進行摻雜改性,MWCNTs使用前進行酸化處理,以改善其在水溶液中的分散性。制備了不同MWCNTs摻雜量的PEDOT:PSS/MWCNTs復合薄膜,實驗結果表明MWCNTs摻雜提高了PEDO T:PSS的導電性能,降低了其透光性能,且最佳摻雜量為0.5%。實驗還發(fā)現(xiàn)玻璃基底薄膜的方阻值均小于PET基底的方阻值,且都在MWCNTs摻雜量為0.5%時,取得最小方阻值,分別為309.70Ω/□和341.50Ω/□。UV測試表明,由于MWCNTs在可見光波段的吸收作用及薄膜內部網(wǎng)絡構造的阻擋作用,致使MWCNTs摻雜后PEDOT:PSS薄膜的透光率降低至45.28%。(3)選用導電銀漿對PEDOT:PSS進行摻雜改性,用二甲苯溶劑,按VAg:V二甲苯=1:1.5比例稀釋導電銀漿。研究了超聲分散處理時間對Ag顆粒尺寸的影響,結果表明,銀顆粒尺寸隨著超聲分散時間的增加先減小后增大。采用靜電紡絲裝置成功制備了PEDOT:PSS/Ag、PEDOT:PSS/Ag/PEDOT:PSS、Ag/PEDOT:PSS三種復合薄膜。復合Ag后PEDOT:PSS薄膜在紫外可見光波段的吸收明顯增加,透光率降低,導電性能提高。
[Abstract]:The discovery of conductive polymers has opened up a new research and application field for this kind of materials. Because of its good conductivity and easy film formation, poly (3n4- ethylenedioxythiophene) / polystyrene sulfonate (PEDOT: PSS) is easy to form films because of its good conductivity. The advantages of good environmental stability, good transmittance and no pollution have become the research focus in the field of conducting polymers. This paper mainly focuses on the preparation and doping modification of PEDOT:PSS conductive polymer films. The main contents are as follows: (1) the effects of electrospinning parameters on the optical properties of PEDOT:PSS films were studied by orthogonal experiment. The optimum spinning process parameters are as follows: voltage 17 kV, receiving distance 13 cm, needle type 8. The electric field distribution was simulated by ANSYS software. The effect of heat treatment temperature on the conductivity of the film was studied. The optimum heat treatment temperature is 120 鈩，
