Tuning Crosslinking of Hybrid Preceramic Polymers in Vat Photopolymerization Toward Controlled Ceramic Yields

Invention Reference Number

202405736

Engineering advances in ceramics derived from preceramic polymer processing provide promising potential in materials science, chemical engineering, and manufacturing science for their versatility and tunability. Preceramic polymers, typically consisting of silicon, carbon, and other elements, can undergo pyrolysis to yield polymer-derived ceramics (PDCs) with tailored properties suited for a wide range of applications, including aerospace, electronics, biomedicals, and energy storage [1-6]. Many preceramic polymers can undergo crosslinking prior to pyrolysis or other thermoprocessing. Understanding the role of crosslinking in the precursor polymer network is critical for the successful organic-to-inorganic conversion of preceramic polymers into ceramic materials. Crosslinking, the formation of interconnecting bonds across separate polymer chains, augments the structural integrity and thermal stability of the polymeric material.
