INKS FOR 3D PRINTING GRADIENT REFRACTIVE INDEX (GRIN) OPTICAL COMPONENTS |
摘要 |
Optical inks suitable for 3D printing fabrication of gradient refractive index (GRIN) optical components are composed a monomer matrix material doped with ligand-functionalized nanoparticles, wherein the monomer has a viscosity less than 20 cPoise and is UV curable to form a solid polymer. The matrix material doped with the ligand-functionalized nanoparticles has a transmittance of at least 90% in a predetermined optical wavelength range, wherein the ligand functionalized nanoparticles have a size less than 100 nm, are loaded in the monomer matrix material at a volume percent of at least 2%, and alter an index of refraction of the monomer matrix by at least 0.02. The ligand-functionalized nanoparticles have a plurality of ligands attached to a nanoparticle core surface with an anchor functional group and terminated with a buoy functional group that are reactive, non-reactive, or combinations thereof. In some embodiments the ligands have a length less than 1.2 nm measured radially from the nanoparticle core surface. |
