Formation of Nanoparticle-Loaded Microcapsules Based on Hydrogen-Bonded Multilayers

摘要: We show that hydrogen-bonded multilayer thin film coatings assembled on colloidal particles can be used as templates for the in situ synthesis of nanoparticles. The concentration and size nanoparticles grown within tuned by number loading cycles. films were coated polystyrene micrometer-sized subsequently cross-linked via water-soluble carbodiimide chemistry. metal (e.g., Ag Pd) synthesized nanoreactor scheme, where corresponding ions are loaded into coating then reduced to create dispersed coating. In addition, we demonstrate multiple capability coatings. UV−vis spectroscopy direct observation transmission electron microscopy confirm well-dispersed Finally, extracted treati...
