Web19 aug. 2014 · Maintaining hierarchical roughness and a low surface energy property are keys to long lasting superhydrophobic surfaces. By spraying polystyrene/SiO2 core/shell nanoparticles as a coating skeleton and polydimethylsiloxane as hydrophobic interconnection, lasting and self-healing superhydrophobic surfaces were fabricated. … Web10 okt. 2024 · A new procedure for the functionalization of melamine sponge (MeS) with urea-formaldehyde (UF) co-oligomers is put forward. The procedure differs from the typical synthesis of the UF co-polymer, as it employs a base-catalyzed condensation step at certain concentrations of urea and formaldehyde. The produced melamine-urea-formaldehyde …
