- Abstract
This essay analyses the experiment of xylene, ethyl acetate and acetone as solvent materials influencing the surface resistivity and electromagnetic shielding effectiveness of conductive filler composite material, as well as the main reasons for this difference from the perspective of material properties of the solvent. Analysis shows that, when the acrylic is the resin-based material, all three solutions can be used as a solvent to adjust the viscosity of the coating electromagnetic shielding. However, there is a huge difference in shielding effectiveness after spraying. This essay found that the dielectric constant has an important influence on the shielding effectiveness. While acetone is the solvent with the largest dielectric constant, the electromagnetic shielding effectiveness is worst. While xylene is a solvent, the electromagnetic shielding effectiveness is the best, and the volume fraction variation does not affect the electromagnetic shielding effectiveness. While ethyl acetate is a solvent, the influence is more complicated. There is need for a comprehensive analysis on the mobility and film-forming properties.
