Abstract：

Developing　dual-function　materials　with　efficient　electromagnetic　wave　absorption　and　good　thermal　conductivity　to　achieve　excellent　packaging　of　devices　has　considerable　appeal　in　modern　electronic　devices.　Co-MOF-74　derivatives/polyacrylamide　bifunctional　gels　(PAM-x)　were　synthesized　by　magnetic　field　assisted　technique　and　in　situ　radical　polymerization.　PAM-x　showed　a　minimum　reflection　loss　(RLmin)　of　−51.6　dB　and　a　maximum　effective　absorption　bandwidth　(EAB)　of　5.73　GHz　at　a　low　filler　loading　of　5　wt%.　The　magnetic　nanoparticles　in　the　MOF　derivatives　orient　the　fillers　in　the　polymer　matrix　under　the　action　of　the　magnetic　field　to　form　an　ordered　thermal　conductivity　path,　which　improves　the　thermal　conductivity　perpendicular　to　the　plane　direction　and　helps　to　promote　rapid　heat　transfer.　This　work　highlights　the　potential　of　MOF　derivatives/polymers　as　bifunctional　gels,　and　also　provides　a　reference　for　the　trade-off　between　electromagnetic　wave　absorption　and　thermal　conductivity.　©　2023　Elsevier　Ltd
