Abstract
ABSTRACT Metal-doped polymer derived ceramics (PDCs) exhibits multifunctional properties due to the introduction of special metal element; however as one of the cheapest metal element carriers, metal inorganic salts have rarely been reported for the fabrication of metal-doped PDCs. In this article, a novel hydrophilic photosensitive γ-methacryloxypropyl trimethoxy modified polyhydroxymethylsiloxane preceramic polymer was firstly synthesised and three different metal-doped SiOC ceramic lattices with a strut thickness of 200 μm were successfully fabricated using inorganic metal salts as the metal source by digital light processing. The photosensitive coefficient, initial photocuring coefficient and the corresponding working curves were employed to evaluate the photocurable ability of preceramic polymers with different recipes. Results showed that both the metal-containing polymer lattices and the metal-doped SiOC ceramic lattices exhibited high-resolution microstructure and homogeneous metal element distribution, indicating that the inorganic metal salt is an effective metal source for the fabrication of metal-doped PDCs.
