The ever-increasing electromagnetic interference (EMI) pollution becomes an important issue in current environmental protection and human society. In this work, 3D BaTiO3(3DBT)@C porous ceramic framework was one-step fabricated by sol-gel method using environmentally friendly cleanroom wipers as template and calcined under inert atmosphere. Subsequently, epoxy (EP) resin was reversely incorporated into the above 3DBT@C network, resulting in the 3DBT@C/EP composite. Results showed that the cleanroom wiper was calcined and transformed into amorphous carbon within the 3DBT, leading to the excellent electrical conductivity of 3DBT@C. The reverse infiltration of EP maintained the successive 3DBT framework and excellent conductivity, thus endowing the 3DBT@C/EP composite with a good electromagnetic interference shielding effectiveness (EMI SE) as high as 36.6 dBꞏmm-1 at 10.2 GHz. The absorption mechanism of EMI prevailed the EMI SE due to the large Ohmic loss and porous 3D network, implying potential applications in flexile shielding materials. |
