The UK Government has set targets for the reduction of CO2 emissions of 80 % by 2050. Post-combustion capture of CO2 from power plants is key if we are to achieve these targets. Post-combustion CO2 capture is challenging due to the low concentration of CO2 in the waste stream and the presence of impurities (H2O, NOx, SOx, etc). Post-combustion capture adds energetic cost via the requirement to capture and compress the CO2. Amine-based scrubbing processes are being evaluated for post-combustion CO2 capture. This is a costly process, and the amines are corrosive. Other candidate technologies include physical adsorption into solid sorbents coupled with pressure-swing or temperature-swing adsorption/desorption. In principle this may lower the energy overhead, but the volume of sorbent required is extremely large, limiting the range of sensible materials. Membrane-based processes have potential advantages over the above. In particular, there are no losses due to heat required to regenerate and release CO2 from the spent sorbent or solvent, and the footprint for the technology and amount of material required is comparatively small.Here, we will develop advanced mixed matrix membranes (MMMs) technology utilising organic fillers, rather than inorganic fillers, that could be cost-effectively fitted to power plants to separate and capture CO2. There has been much research on inorganic-organic MMMs, using fillers such as zeolites and MOFs. However, it is challenging to achieve a homogeneous dispersion of the inorganic filler particles in the polymer matrix. This is exacerbated by the lack of compatibility between most fillers, which are frequently crystalline inorganic or metal-organic materials, and the membrane polymers, which are invariably amorphous and organic. We build therefore on our unique report of organic-organic MMM (Angew Chem Int Ed, 2013) , where excellent dispersion of the organic filler was found and there was good adhesion between the organic polymer and the organic filler, both of which are predominantly aromatic structures. We address this by bringing together two UK groups who have pioneered in the development of novel porous membranes (Budd) and new microporous organic materials (Adams, Cooper).

英国政府设定了到 2050 年将二氧化碳排放量减少 80% 的目标。如果我们要实现这些目标，从发电厂燃烧后捕获二氧化碳是关键。由于废物流中 CO2 浓度低且存在杂质（H2O、NOx、SOx 等），燃烧后 CO2 捕获具有挑战性。燃烧后捕获由于需要捕获和压缩二氧化碳而增加了能源成本。正在评估基于胺的洗涤工艺用于燃烧后二氧化碳捕获的效果。这是一个成本高昂的过程，而且胺具有腐蚀性。其他候选技术包括物理吸附到固体吸附剂中，并结合变压或变温吸附/解吸。原则上，这可以降低能量开销，但所需吸附剂的体积极大，限制了敏感材料的范围。基于膜的工艺比上述工艺具有潜在的优势。特别是，从用过的吸附剂或溶剂中再生和释放二氧化碳所需的热量不会造成任何损失，而且技术占地面积和所需材料量相对较小。在这里，我们将开发先进的混合基质膜 (MMM)该技术利用有机填料而不是无机填料，可以经济有效地安装到发电厂中以分离和捕获二氧化碳。人们对使用沸石和 MOF 等填料的无机-有机 MMM 进行了大量研究。然而，实现无机填料颗粒在聚合物基体中的均匀分散具有挑战性。由于大多数填料（通常是结晶无机或金属有机材料）与膜聚合物（总是无定形和有机材料）之间缺乏相容性，这一问题更加严重。因此，我们以我们独特的有机-有机 MMM 报告（Angew Chem Int Ed，2013）为基础，其中发现有机填料具有出色的分散性，并且有机聚合物和有机填料之间具有良好的粘附性，两者主要都是芳香族结构。我们通过将两个在新型多孔膜（Budd）和新型微孔有机材料（Adams、Cooper）开发方面处于领先地位的英国团队聚集在一起来解决这个问题。
