摘要: 以新型高导电性二维纳米材料Ti3C2Tx MXene作为导电填料以芳纶纳米纤维ANF作为气凝胶的增强材料用冷冻干燥法先构筑多孔的三维导电MXene/ ANF气凝胶作为骨架再回填硅橡胶PDMS制备MXene/ANF/PDMS复合材料研究了不同MXene/ANF填料配比对材料的形态导电性电磁屏蔽EMI性能力学性能的影响结果表明通过回填法制备的复合材料界面相容性良好PDMS的回填没有造成气凝胶的塌陷破碎MXene/ANF/PDMS复合材料在2.89%质量分数的低填料量下且厚度为1.8 mm时就能获得高电导率9.03 S · cm-1电磁屏蔽效能可达到40.4 dB屏蔽效率高达99.991%并具有优秀的压缩力学性能

Abstract Ti3C2Tx MXene was used as conductive filler and aramid nanofiber ANF was used as aerogels reinforcement materialthe porous three-dimensional conductive MXene/ANF aerogel was constructed as the skeleton by freeze-drying methodthen backfilled silicone rubber PDMS to prepare the MXene/ANF/PDMS composites. The influences of different MXene/ANF filler ratio on the morphologyconductivityelectromagnetic interference EMI shielding performancemechanical properties of the materials were studied. The results show that the composites prepared by backfilling method had good interface compatibilityand the backfilling of PDMS did not cause the collapse and breakage of aerogel. The MXene/ANF/PDMS composites obtained high conductivity 9.03 S · cm-1 and superior EMI-shielding effectiveness EMI SE of 40.43 dB with the loading of 2.89% and the thickness of 1.8 mmand achieved outstanding shielding efficiency Aeff of 99.991%and exhibited excellent compressive mechanical properties.
