Effect of the Particle Size and Layer Thickness of GNP Fillers on the Dielectric Properties and Actuated Strain of GNP?PDMS

초록

The increase in permittivity was the highest at 4.26 (103 Hz) when M25 grade GNP with the largest particle size was added. ? M25 grade GNP, which has the largest aspect ratio at 4166.6, has the largest actuated strain value of 3.01% (3kV/mm). ? As the ratio of the particle size to the layer thickness of GNP is large, and the aspect ratio increases, the dielectric constant and actuated strain value increase.
