Hybrid polymer compounds (1–x)CsH₅(PO₄)₂-xButvar (polyvinyl butyral brand Butvar®) (x = 0–0.3, x - weight fraction), synthesized with ethanol and isopropanol as solvents, studied using the electrochemical impedance method, powder X-ray diffraction analysis (XRD hereinafter), differential scanning calorimetry, and electron microscopy. A more optimal synthesis method was determined and the fundamental possibility of creating new highly conductive thin polymer electrolytes based on CsH₅(PO₄)₂ was shown. The crystal structure of the CsH₅(PO₄)₂ (P2₁/c) salt remains unchanged in the polymer hybrid system, but dispersion and partial amorphization of salt were observed during synthesis. It was found that, to achieve the highest proton conductivity of (1–x)CsH₅(PO₄)₂-xButvar, the most preferable method of synthesis is the precipitation of the salt, from the starting components, in the presence of a solvent common with the polymer. The most optimal is the method of salt precipitation from a polymer solution in ethanol as a common solvent with further tape casting. The thickness of polymer electrolytes is no more than 50–100 μm. Proton conductivity increases by 2 orders of magnitude relative to the initial salt and depends on composition, uniformity of salt distribution in the polymer volume, and the presence of residual humidity during electrolyte synthesis. The highest proton conductivity was 10^-2 S/cm at 130 °C at low humidity conditions. Changes in the electrotransport characteristics of the system are caused by dispersion and partial amorphization of the salt, as well as by the presence of insignificant amounts of residual water molecules on the salt surface under the conditions of the synthesis of polymer compositions.

杂化高分子化合物 (1–x)CsH ₅ (PO ₄ ) ₂ -xButvar（聚乙烯醇缩丁醛品牌 Butvar®）（x = 0–0.3，x - 重量分数），以乙醇和异丙醇为溶剂合成，使用电化学阻抗进行研究方法，粉末X射线衍射分析（以下简称XRD），差示扫描量热法和电子显微镜。确定了一种更优化的合成方法，并展示了基于 CsH ₅ (PO ₄ ) _{2 的}新型高导电薄聚合物电解质的基本可能性。CsH ₅ (PO ₄ ) ₂ (P2 ₁/c) 盐在聚合物杂化体系中保持不变，但在合成过程中观察到盐的分散和部分非晶化。结果表明，为了达到 (1-x)CsH ₅ (PO ₄ ) ₂的最高质子传导率-xButvar，最优选的合成方法是在聚合物常见的溶剂存在下，从起始组分中沉淀盐。最理想的方法是从作为常见溶剂的乙醇中的聚合物溶液中沉淀盐，并进一步流延。聚合物电解质的厚度不超过50-100μm。质子电导率相对于初始盐增加 2 个数量级，并取决于组成、聚合物体积中盐分布的均匀性以及电解质合成过程中残留湿度的存在。最高质子传导率为10 ^-2S/cm 在 130 °C 低湿度条件下。系统电传输特性的变化是由盐的分散和部分非晶化以及在聚合物组合物合成条件下盐表面存在微量残留水分子引起的。
