Hyperporous carbon-coated 3D printed devices

3D printing by stereolithography (SLA) typically leads to low surface area materials, limiting the application of this advanced manufacturing technique for the extraction of environmental pollutants. Here, a simple and efficient procedure to immobilize highly porous materials on SLA 3D printed devices has been developed using a hypercrosslinked pyrrole-derived hyperporous carbon (HCP-carbon) with a surface area of 3361 m² g⁻¹. The HCP-carbon is directly immobilized to the soft and sticky surface of non-post cured SLA 3D printed devices. The HCP-carbon becomes permanently immobilized to the 3D printed device after UV post curing, obtaining a highly robust and efficient support for the removal of pollutants from water.
