Fabrication of composite microstructures by capillarity-driven wetting of aligned carbon nanotubes with polymers

摘要: The interaction, or wetting, of long aligned carbon nanotube (CNT) forests with off-the-shelf (no solvent added) commercial thermoset polymers is investigated experimentally. A technique for creating vertically CNT composite microstructures various shapes presented. effective wetting the forests, as evidenced by a lack voids, three widely varying viscosities supports feasibility using in large-scale hybrid advanced architectures. Among routes identified polymer to penetrate forest, capillarity-driven along axis preferred route. Aligned are useful many applications including test structures direct mechanical and multifunctional property characterization CNT?polymer materials.
