Abstract
An anisotropic composite film includes a plurality of effectively parallel lines of particles with a polymeric or other solid matrix. The composite films are prepared by dispersion of the particles within a precursor to the matrix, such as a monomer, and acoustically stimulating the dispersion to form effectively parallel lines of the particles that are fixed by polymerizing the monomer or otherwise solidifying a matrix. The composite film is anisotropic and the transmittance of the composite film can exceed 50%. The composite films can be rigid or flexible. The composite film can be electrically conductive. The composite films can be employed as transparent electrodes for, displays, solar cells, and wearable devices.
