Primary Applications
Nanoparticle Manufacturing
  • Quantum Dots: Capping agent for size control and aggregation prevention
  • Metal Nanoparticles: Surface stabilization for gold, silver, and other metals
  • Nano-ceramics: Manufacturing of ceramic nanoparticles
Surface Coating & Functionalization
  • Forms condensed hydrophobic monolayers on metal oxide surfaces
  • Anchors to TiO₂, Al₂O₃, Fe₂O₃ surfaces via phosphonic acid group
  • Provides hydrophobic outer layer via hexyl chain
  • Dispersion agent for carbon nanotubes (MWCNTs)
  • Surface modification of barium titanate for dielectric pastes
Surfactant & Capping Agent Functions
  • Controls particle size and morphology during synthesis
  • Prevents nanoparticle agglomeration in suspension
  • Tunes surface hydrophobicity/hydrophilicity
Surface Binding Mechanism

The phosphonic acid group binds strongly to metal oxide surfaces through:

  • Condensation reactions with surface hydroxyl groups (M-OH)
  • Formation of P-O-M bonds (M = Ti, Al, Fe, Zr metal atoms)
  • Multidentate binding as mono-, bi-, or tridentate ligand

This strong binding combined with the hydrophobic hexyl chain enables creation of self-assembled monolayers with controlled surface properties.
