Hierarchically Porous Coatings for Cellulose Fibers by Core–Shell Particle Templating
Macromolecular Rapid Communications, EarlyView.Hybrid and functional core–shell particles comprising a silica core and a polymer shell were synthesized and used to develop a coating and etching process applied to a cellulose substrate. This resulted in highly porous, functional coatings on a cellulose membrane for further application in cellulose‐based adsorbers and advanced membrane technology ...
