A method has been developed for the fabrication of a polymer-inorganic composite material based on the Celgard polymer matrix by means of the introduction of silica nanoparticles with amino groups into the polymer structure through impregnation of the porous structure with solutions of the aminosilane precursor in supercritical СO2. The presence of inorganic nanoparticles made it possible to noticeably enhance the hydrophilicity of the material, and the absolute wettability of supercritical CO2 was favorable for uniform particle distribution in membrane pores. The particles growing in membrane pores allowed one to reduce the pore size, which opens ways to control ion-transport selectivity.

从（氨基丙基）三乙氧基硅烷在超临界二氧化碳中的溶液获得的基于 Celgard 基质的聚合物-无机复合材料

开发了一种制备基于 Celgard 聚合物基体的聚合物-无机复合材料的方法，该方法通过在超临界条件下用氨基硅烷前体溶液浸渍多孔结构，将带有氨基的二氧化硅纳米粒子引入聚合物结构中。 O2。无机纳米粒子的存在可以显着提高材料的亲水性，超临界 CO2 的绝对润湿性有利于粒子在膜孔中的均匀分布。在膜孔中生长的颗粒可以减小孔径，这为控制离子传输选择性开辟了道路。
