The successive deposition of a controlled number of 1 nm thick monolayers of a polymer of intrinsic microporosity (PIM) on top of thick films of the ultra-permeable poly[1-(trimethylsilyl)-1-propyne] is an effective method to obtain composite polymeric membranes for CO₂/N₂ separation in post-combustion conditions. The use of only 0.04 % of PIM dense membrane content in the selective layer allows increased CO₂ permeance and reduced membrane size and energy cost.

超薄复合聚合物膜，用于最小厚度和高CO2渗透率的CO2 / N2分离

在超渗透性聚[1-（三甲基甲硅烷基）-1-丙炔]厚膜的顶部连续沉积受控数量的1 nm厚的本征微孔性（PIM）聚合物单层是获得复合材料的有效方法燃烧后条件下用于分离CO ₂ / N _2的聚合物膜。在选择性层中仅使用0.04％的PIM致密膜含量可提高CO ₂渗透率并降低膜尺寸和能源成本。
