Synthesis of a 3D graphite microball using a microfluidic droplet generator and its polymer composite with core–shell structure†
Abstract
Spherical 3D graphite microballs (3D GMs) and their nanohybrids (3D GM–Fe3O4 nanoparticles) were synthesized by using a microfluidic droplet generator and a thermal evaporation-induced capillary compression method. Using the 3D GM–Fe3O4 nanoparticle as a support for polymerization, 3D GM–polypyrrole composites were produced with a unique core–shell structure.
