隨著時代的進步，電器產品蓬勃發展，電池成為與我們生活中密不可分的物品之一，在電解質的研究中，離子液體具有高導電度，低揮發，高熱穩定度等特性，並將其與高分子混合，形成聚電解質，應用在電池、電容上也日新月異。本次實驗中，我們可以看到不同濃度[EMIM][TFSI]與[HMIM][TFSI]離子液體和PVDF-co-HFP高分子的混合，在常壓下，離子液體陽離子咪唑環(imidazolium) 4、5號C-H鍵的波數，隨著離子液體濃度的下降而上升，波數從3158.4cm-1到3163cm-1，陰離子[TFSI]在C-F鍵上的波數則沒有太大的變化。在高壓中，更能看到陽離子咪唑環C-H鍵波數的變化，從3171.2 cm-1到3186.3cm-1，比常壓下更加明顯，且隨著壓力越大，出來的圖譜也與常壓下，低濃度離子液體圖譜越來越相似，在紅外光譜中，除了波數的增加和波峰的改變，並無看到其他的訊號峰，因此可以證明[EMIM][TFSI]與[HMIM][TFSI]兩離子液體與PVDF-co-HFP高分子只有物理作用而沒有化學作用，且PVDF-co-HFP較易與離子液體的陽離子發生作用。

With the development of the times, electrical products have developed vigorously, and batteries have become one of the inseparable items in our lives. In the research of electrolytes, ionic liquids have characteristics such as high electrical conductivity, low volatility, and high thermal stability. Polymers are mixed to form polyelectrolytes, which are also used in batteries and capacitors. In this experiment, we can see different concentrations of [EMIM] [TFSI] and [HMIM] [TFSI] ionic liquids and PVDF-co-HFP polymers. Under normal pressure, the ionic liquid cationic imidazole ring (imidazolium) The wave number of CH bond Nos. 4 and 5 increased as the concentration of the ionic liquid decreased, and the wave number was from 3158.4 cm-1 to 3163 cm-1. The wave number of the anion [TFSI] on the CF bond did not change much. At high pressure, the change in the number of CH bond waves of the cationic imidazole ring can be seen more, from 3171.2 cm-1 to 3186.3 cm-1, which is more obvious than under normal pressure, and as the pressure increases, the resulting spectrum is also similar to normal pressure. At this time, the low-concentration ionic liquid spectra are becoming more and more similar. In the infrared spectrum, except for the increase of wave number and the change of the peak, no other signal peaks are seen, so it can be proved that [EMIM] [TFSI] and [HMIM] [TFSI] The two ionic liquids and PVDF-co-HFP polymers have only physical and no chemical interactions, and PVDF-co-HFP is more likely to interact with the cations of ionic liquids.
