Generally, the present invention provides methods for the production of materials comprising a plurality of nanostructures such as nanotubes (e.g., carbon nanotubes) and related articles. The plurality of nanostructures may be provided such that their long axes are substantially aligned and, in some cases, continuous from end to end of the sample. For example, in some cases, the nanostructures may be fabricated by uniformly growing the nanostructures on the surface of a substrate, such that the long axes are aligned and non-parallel to the substrate surface. The nanostructures may be, in some instances, substantially perpendicular to the substrate surface. In one set of embodiments, a force with a component normal to the long axes of the nanostructures may be applied to the substantially aligned nanostructures. The application of a force may result in a material comprising a relatively high volume fraction or mass density of nanostructures. In some instances, the application of a force may result in a material comprising relatively closely-spaced nanostructures. The materials described herein may be further processed for use in various applications, such as composite materials (e.g., nanocomposites). For example, a set of aligned nanostructures may be formed, and, after the application of a force, transferred, either in bulk or to another surface, and combined with another material (e.g., to form a nanocomposite) to enhance the properties of the material.

Corrosion-resistant coatings and methods of making and using the coatings are provided. The corrosion-resistant coating includes magnetic particles dispersed in a polymer matrix, where the polymer matrix is non-polar and at least partially hydrophobic and the magnetic particles contain an adhesion region comprising a ferromagnetic material, and a polymer interface region surrounding the adhesion region comprising a plurality of ligands, where each ligand comprises an anchoring end and a non-polar end. Methods of producing corrosion-resistant articles are also provided. The methods include applying a corrosion-resistant coating to an article and curing the coating.
