【摘要】：利用電解解離的方法研究層層組裝氫鍵復合薄膜(PEOX/PAA)的解離行為,將制備在導電ITO玻璃上的薄膜放置于電解池的正極進行解離,實驗后得到均勻平坦而非粗糙的薄膜。通過衰減全反射(ATR)和循環(huán)伏安法(CV)分析可知,引起氫鍵薄膜解離的是正極附近形成的pH梯度區(qū)間,即靠近電極呈酸性、遠離電極呈堿性。此外,對比薄膜在電解池正負極的解離行為,進一步證明正負極附近形成的不同pH梯度區(qū)間導致薄膜解離形貌和厚度差異的產(chǎn)生。電解液的pH以及電解電壓均影響氫鍵薄膜在正極的解離行為,通過分析提出了一個較為適宜的電解解離條件。
[Abstract]:The dissociation behavior of layer upon layer assembled hydrogen-bonded composite film (PEOX/PAA) was studied by electrolysis method. The film deposited on conductive ITO glass was placed on the positive electrode of the electrolysis cell for dissociation, and the uniform flat film was obtained after the experiment. Through the analysis of attenuated total reflection (ATR) and cyclic voltammetry (CV), it is found that the dissociation of hydrogen bond films is caused by pH gradient near the positive electrode, that is, it is acidic near the electrode and alkalescent away from the electrode. In addition, by comparing the dissociation behavior of the film in the cathode and cathode in the electrolysis cell, it is further proved that the different pH gradient region near the positive and negative electrode leads to the difference in the morphology and thickness of the film. The pH of the electrolyte and the electrolytic voltage all affect the dissociation behavior of the hydrogen bonding film at the positive electrode.
