Popis

General description

(3-Mercaptopropyl) trimethoxysilane (MPS) is predominantly used as a precursor for silica.

(3-mercaptopropyl)trimethoxysilane (MPTMS) is an organosilane with a thiol group, which can be used as a self-assembled monolayer (SAM). It can be used as a conjunction reagent to immobilize a variety of nanoparticles.

Application

MPTMS can be coated with TiO₂, CeO₂ and La₂O₃ for protection against corrosion on quaternary bronze in urban atmosphere. It can also be used as a silica nanofluid (NF) to modify the surface of berea sandstone to improve the enhanced oil recovery (EOR) area in the petroleum industry. MPTMS forms composites with kaolin, that can be used as an absorbent for the removal of heavy metals from wastewater. MPTMS can form a bilayer with multiwalled carbon nanotubes (MWNTs) on gold electrodes which can be used to study the electrochemical properties of fluphenazine.
