Air and water pollution poses a serious threat to public health and the sustainable development of the ecological environment. Here, we report the fabrication of new low-resistance nanofilters based on thiophene-based conjugated microporous polymer (T-CMP) nanotubes to remove harmful particulate matter (PM) from air effectively. T-CMP nanotube filters feature inherent superhydrophobicity and hierarchical pores and are prepared by a facile one-pot synthesis. The PM removal efficiency of T-CMP nanotube filters at 90 ± 5% relative humidity exceeds 99.798 ± 0.055% for PM_0.3 and 99.998 ± 0.002% for PM_2.5, while the lowest pressure drop in the filtration system is only 5 Pa, which is 1–2 orders of magnitude lower than that of traditional fiber-based filters. Benefitting from their excellent porous feature and intrinsic superhydrophobicity, T-CMP nanotube filters also display higher flux during continuous oil–water separation. Based on this superior separation performance, better physicochemical stability, facile manufacturing, and easy scaling-up, such T-CMP nanotube filters might hold great potential for a wide range of applications even under harsh conditions, including PM removal, water treatment, and so on.

低电阻噻吩基共轭微孔聚合物纳米管滤池，可有效捕获颗粒物和油/水分离

空气和水污染严重威胁公共卫生和生态环境的可持续发展。在这里，我们报道了基于噻吩基共轭微孔聚合物（T-CMP）纳米管的新型低阻纳米过滤器的制造，以有效去除空气中的有害颗粒物（PM）。T-CMP纳米管滤光片具有固有的超疏水性和分级孔隙，并通过简便的一锅法合成制备。在90±5％相对湿度下，T-CMP纳米管过滤器的PM去除效率对于PM _0.3超过99.798±0.055％，对于PM _2.5超过99.998±0.002％，而过滤系统中的最低压降仅为5 Pa，比传统的基于纤维的过滤器低1-2个数量级。得益于其出色的多孔性和固有的超疏水性，T-CMP纳米管过滤器在连续油水分离过程中也显示出更高的通量。基于这种出色的分离性能，更好的理化稳定性，易于制造和易于放大的规模，此类T-CMP纳米管过滤器即使在苛刻的条件下（包括去除PM，水处理等）也可能具有广泛的应用潜力上。
