Název v původním jazyce

Electrically conductive aluminosilicate/graphene nanocomposite

Popis výsledku v původním jazyce

Highly electrically conductive ceramic material based on aluminosilicate/graphene nanocomposite has been prepared by high pressure (400 MPa)compaction of montmorillonite intercalated with polyaniline followed with the high temperature (1400 degrees C) treatment in argon atmosphere. Tabletspressed from polyaniline/montmorillonite intercalate exhibits strong texture due to the disk-shaped montmorillonite particles and, consequently,the high anisotropy in conductivity. The high temperature induced phase transformation of montmorillonite into cristobalite and mullite preservedthe aluminosilicate layered structure and created good conditions for formation of graphene sheets from polyaniline layers intercalated in montmo-rillonite. Therefore, the texture andanisotropy in conductivity remain preserved in resulting aluminosilicate/graphene tablets, while the in-planeconductivity in aluminosilicate/graphene tablets is 23,000x higher than the conductivity of uncalcined polyaniline/montmorilloni
