  • CONTROL OF NANOPARTICLES DISPERSION STABILITY THROUGH DIELECTRIC CONSTANT TUNING, AND DETERMINATION OF INTRINSIC DIELECTRIC CONSTANT OF SURFACTANT-FREE NANOPARTICLES
    Publication number: 20230287195
    Abstract: A composition including a medium and surfactant-free nanoparticles (SFNPs) at different dispersion state or aggregation form. The composition includes: (a) a composition of a medium and surfactant-free nanoparticles in primary form, wherein the dielectric constant value (DE value) of the medium is equal to or larger than the intrinsic dielectric constant value (IDE) of the SFNPs and smaller than about 1.

  • SYNTHESIS, PURIFICATION, AND PROPERTIES OF RING-OPENED BENZOXAZINE THERMOPLASTIC
    Publication number: 20230159705
    Abstract: A crosslinkable thermoplastic resin composition may include a polymer formed from the reaction between a bis-benzoxazine monomer and a bifunctional comonomer having phenol, amine, and/or thiol functional groups, wherein the polymer contains at least one crosslinkable group. A method of forming a crosslinkable thermoplastic resin composition may include reacting a bis-benzoxazine monomer and a bifunctional comonomer to form a polymer containing at least one crosslinkable group. A method of forming a cured thermoplastic resin may include curing the crosslinkable thermoplastic resin composition by applying an external stimulus.

  • CONTROL OF NANOPARTICLES DISPERSION STABILITY THROUGH DIELECTRIC CONSTANT TUNING, AND DETERMINATION OF INTRINSIC DIELECTRIC CONSTANT OF SURFACTANT-FREE NANOPARTICLES
    Publication number: 20180327566
    Abstract: A composition including a medium and surfactant-free nanoparticles (SFNPs) at different dispersion state or aggregation form. The composition includes: (a) a primary form, wherein the dielectric constant value (DE value) of the medium is equal to or larger than the intrinsic dielectric constant value (IDE) of the SFNPs and smaller than about 1.5 times of the IDE of the SFNPs; (b) a reaction-limited aggregation form of SFNPs, wherein the DE value of the medium is much larger than the IDE of the surfactant-free nanoparticles; (c) a diffusion-limited aggregation form of SFNPs, wherein the DE value of the medium is smaller than the IDE of the surfactant-free nanoparticles; and (d) a redispersible aggregation form of surfactant-free nanoparticles, wherein the surfactant-free nanoparticles are induced to aggregate in the diffusion-limited fashion in a medium with a DE value that is smaller than the IDE of the surfactant-free nanoparticles.
