摘要：

We review preparation and properties of confined, aligned string-like particle assemblies formed by dielectrophoresis under alternating electric fields. Particular attention is placed on carbon particles aligned in the oligomer matrix. In these systems the particle fraction is low, below the isotropic percolation threshold. The matrix is polymerized after alignment, which locks the aligned strings in place. Application examples are discussed including particle separation, conductivity enhancement and piezoresistive sensors.
