3D-printed nanocomposites with metal diboride nanosheets
A polymerizable composition for 3D printing includes a photocurable polymer resin and metal diboride nanosheets. The resulting polymer nanocomposite includes a polymer matrix and metal diboride nanosheets dispersed throughout the polymer matrix. A method of synthesizing a nanomaterial-containing resin for 3D printing includes preparing a dispersion of metal diboride nanosheets in a solvent, and combining the dispersion with a liquid polymer resin to yield the nanomaterial-containing resin. A method of fabricating a nanocomposite structure from the nanomaterial-containing resin includes providing the nanomaterial-containing resin to a three-dimensional printer, forming a three-dimensional structure with the three-dimensional printer, and processing the three-dimensional structure to yield the nanocomposite structure.
