Percolative silver nanoplates/PVDF nanocomposites: Bulk and surface electrical conduction
Abstract : Electrically conductive polymer composites have been elaborated by dispersing silver microplates into a
polyvinylidene fluoride (PVDF) matrix. Silver microplates have been successfully synthesized. Their mean
lateral length is about 1.15 mm, presenting a moderate aspect ratio (12e25). Synthesis is easily controlled
and can produce 1e500 mg depending on the volume and the concentration of the solutions used.
Electrical bulk and surface conductivity of the composites containing different filler fractions (4e20
vol.%) have been determined for each sample. Electrical percolation has been observed for each situation
and was determined at 5.9 vol.% for bulk conductivity (through the thickness), while the value is shifted
to 6.9 vol.% when surface conductivity is considered. The gap between the two values of percolation
threshold is attributed to the orientation of fillers. Bulk conductivity and surface resistivity reaches
12.9 S m�1 and 0.123 U/☐ respectively at filler fraction of 15 vol.%.
