Description
Summary:On page 4876, Y. Wang and co‐workers demonstrate a novel bacteria filter which combines the advantages of size filtration by macroporous structure and a photothermal effect by an NIR‐sensitive material. A strategy based on tuning the amphiphilicity of an originally hydrophobic block copolymer is proposed, leading to successful preparation with 95 vol% internal volume, in which a concentration of as low as 4 wt% is needed. Open‐cell macroporous monoliths templated from this exhibit remarkable performance for bacteria filtration after coating with polypyrrole nanoparticles.
