Surface reactions on thin layers of silane coupling agents

Surface Reactions on Thin Layers of Silane Coupling Agents

The reactivity of immobilized functional groups in thin layers of (3-aminopropy1)triethoxy~ilane (APS), (3-mercaptopropyl)trimethoxy~ilane, (3-bromopropyl)trimethoxysilane, and (8-bromoody1)trimethoxysilane on oxidized aluminum substrates was studied with reflection-adsorption infrared spectroscopy (RAIR), optical ellipsometry and contact-angle measurements. Mass changes on the surface associat...

[Silane coupling agents].

Synthesis and antimicrobial activity of quaternary ammonium silane coupling agents.

Fourteen novel silane coupling agents with a quaternary ammonium group introduced into the molecule, [CH(2)=CHCH(2)N(+)(CH(3))(C(n)H(2n+1))(CH(2))(3)Si(OCH(3))(3)]X(-) (n-X, n=10-18, X=Cl, Br, or I), were synthesized with the aim of using these agents to make material surfaces antimicrobial for a long period of time. Measurements of the minimum inhibitory concentrations (MIC) against 12 kinds o...

Colloidal assemblies on patterned silane layers.

The site-selective assembly of colloidal polymer particles onto laterally patterned silane layers was studied as a model system for the object assembly process at mesoscale dimensions. The structured silane monolayers on silicon oxide substrates were fabricated by a combination of liquid- and gas-phase deposition of different trialkoxysilanes with a photolithographic patterning technique. By us...
