    Inventors: Dmitry Fomitchev, Hairuo Tu, Paul S. Palumbo, Samir Kumar
  • Publication number: 20230100957
    Abstract: Surface treated silica containing particles are combined with a resin to form a liquid prepolymer composition for use in additive manufacturing. A surface treatment on the silica containing particles may participate in polymerization of the composition. The silica containing particles may be colloidal silica or a silica polymer composite particle.

  • Publication number: 20210380779
    Abstract: Metal oxide-polymer composite particles have a median particle size D50 of 40-75 nm or 100-150 nm and an average RTA of at least 0.06. Alternatively or in addition, metal oxide-polymer composites comprise two or more populations of metal oxide particles differing in size, particle size distribution, or shape. Alternatively or in addition, the use of a multicomponent hydrophobizing system including an alkylsilane to fabricate metal oxide-polymer composite particles increases the tribocharge of the composite particles.
