Particulate　matter(PM)is　a　significant　danger　to　both　environment　and　human　health.Despite　the　development　of　a　series　of　air　filters,they　do　not　work　well　in　harsh　environment　such　as　high　tem-perature,high　humidity　or　long-time　filtration.To　make　a　three-dimensional(3D)particle　capture　de-vice,a　sacrificial　template　approach　was　used　to　manufacture　polydimethylsiloxane(PDMS)sponge,and　then　zeolite　imidazole　framework-8(ZIF-8)was　grown　in　situ　on　the　3D　network　of　PDMS　sponge.The　removal　efficiency　of　PM2.5　or　PM10　is　greater　than　99.8％because　of　the　high　specific　surface　area　and　porous　network　structure　of　PDMS　sponge,as　well　as　the　large　number　of　metal　sites　of　ZIF-8.In　addition,the　sponge　filter　has　long-term　filtration　stability　and　still　achieves　excellent　performance　after　65　h　of　filtration.The　composite　sponge　can　adapt　to　harsh　environments　such　as　high　temperature(250℃)and　high　humidity(90％RH).Composite　sponge　filter　has　a　regular　shape,and　it　may　be　customized　to　any　shape　as　required.This　study　provides　a　new　idea　for　designing　3D　high-efficiency　air　filters　that　can　adapt　to　harsh　environments.
