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.
