For　solid　phase　microextraction　(SPME),　effective　immobilization　of　sorbent　on　a　stainless　steel　fiber　surface　is　very　essential.　But,　it　still　remains　challenging　because　the　chemical　inertness　of　stainless　steel　fiber.　In　this　work,　chemical　bonding　method　was　introduced　to　fabricate　a　series　of　metal-organic　frameworks　(MOFs)-coated　stainless　steel　fibers,　and　some　representative　MOFs　(ZIF-90　(Zn),　MOF-199　(Cu),　MIL-101　(Cr),　MOF-5　(Zn))-coated　stainless　steel　fibers　were　successfully　synthesized.　Such　strategy　can　noticeably　increase　the　mechanical　and　chemical　stability,　and　prolong　the　service　lifetime　due　to　it　combine　the　advantages　of　stainless　steel　fiber　and　chemical　bonding　method.　The　stability　of　MOF-ZIF-90　(Zn)-coated　stainless　steel　fibers　which　were　preparated　by　different　methods　(chemical　bonding　method,　adhesive　method　and　deposition　method)　were　studied,　and　results　showed　the　chemical　bonding　method　proved　the　best　stability.　Based　on　the　ZIF-90　(Zn)-coated　fiber,　the　SPME-GC-MS　method　was　developed　for　detecting　traces　of　polychlorinated　biphenyls　(PCBs)　and　satisfactory　results　were　obtained.　The　linear　ranges　were　0.01-600　ng　L-1　and　the　coefficient　of　determination　was　higher　than　0.993.　The　limits　of　detection　for　the　PCBs　were　0.0013-0.053　ng　L-1.　The　recoveries　for　the　spiked　PCBs　in　the　Minjiang　water,　soil　and　vegetable　oil　samples　were　in　the　range　of　85.9-105.8%.　The　extraction　capacity　of　the　ZIF-90　(Zn)-coated　stainless　steel　fiber　prepared　by　chemical　bonding　method　did　not　show　measurable　change　under　different　temperatures　or　organic　solvents　for　up　to　5　days.　(C)　2018　Elsevier　B.V.　All　rights　reserved.
