氧化石墨烯钼镍氧化物复合材料的制备与性能

氧化石墨烯铝银氧化物复合材料的制

备与性能

摘要：本文探讨了氧化石墨烯钳银氧化物复合材料的制备过程

及其性能表现。石墨烯是一种二维的碳材料，具有独特的电学、

光学和机械性能，但其应用受到单层材料的脆弱性限制。因此,

利用氧化石墨烯与钳银氧化物相结合，可以制备出具有高度穿

透和机械强度的复合材料。本研究采用化学还原法制备氧化石

墨烯，利用溶胶凝胶法制备铝银氧化物，并将两者混合后进行

热处理制备出复合材料，。实验结果表明，复合材料具有较高的

导电性能、穿透率和力学强度，是一种有潜力的透明电极材料。

Introduction

Graphene,atwo-dimensionalcarbonmaterial,has

uniqueelectrical,opticalandmechanicalproperties.

However,itsapplicationislimitedbythefragility

ofsingle-layermaterials.Therefore,thecombination

ofgrapheneoxideandmolybdenum-nickeloxidecanbe

usedtopreparecompositematerialswithhigh

transparencyandmechanicalstrength.Inthisstudy,
