Features of LS-533 Tridecafluorooctyl) Trichlorosilane
1. Extreme Surface Tension Reduction: Effectively lowers the surface energy of substrates, providing superior water and oil repellency (Superhydrophobicity).
2. High-Efficiency SAM Formation: Readily forms high-density Self-Assembled Monolayers (SAMs) on silicon, glass, and metal oxide surfaces via vapor-phase or solution-phase deposition.
3. Exceptional Anti-Sticking Properties: Provides a highly effective release layer for soft lithography and nanoimprint lithography (NIL), preventing polymer adhesion to molds.
4. Chemical & Thermal Resistance: The C-F bond is one of the strongest in organic chemistry, imparting excellent stability against harsh chemicals and UV degradation.
Applications of LS-533 Tridecafluorooctyl) Trichlorosilane
1. Microfluidic Device Fabrication
Extensively used for the silanization of silicon or glass masters in soft lithography. It creates a robust release layer that facilitates the clean removal of PDMS (Polydimethylsiloxane) membranes, essential for manufacturing multi-layer microfluidic chips.
2. Self-Assembled Monolayers (SAMs)
Used to form chemically patterned surfaces for quantitative analysis of surfactants and polymers. It is a preferred reagent for creating cell-adhesive micropatterns and studying neuritogenesis or other cell-surface interactions.
3. Advanced Surface Modification
Applied to steel, glass, and electronic substrates to create superhydrophobic and omniphobic (all-liquid repellent) coatings. This is critical for anti-fouling, anti-icing, and corrosion protection in high-precision industries.
