Aminopropyltrimethoxysilane

Aminopropyltrimethoxysilane (3-Aminopropyltrimethoxysilane; APTMS) (0.5 vol.%; 15 h) forms a highly ordered and uniform self-assembled film on regenerated silicon oxide surfaces, with a thickness of approximately 1.2-1.6 nm (one to two molecular layers), exhibiting uniform elemental distribution at the macroscopic, microscopic, and nanoscale levels, without significant vertical polymerization or island-like structure formation^[1].
Aminopropyltrimethoxysilane (57.20 mmol; 5 h) is successfully grafted onto Pullulan, Viscosity (10%): 15-180 mPa.s (HY-W145522) powder via covalent Si-O-C bonds and siloxane bonds, yielding a modified polysaccharide with an APTMS to anhydroglucose ratio of 0.6, a nitrogen content of 1.8 wt%, and a silicon content of 3.5 wt%^[2].
Aminopropyltrimethoxysilane (1 mM; overnight) adsorbs onto the platinum surface through nitrogen interactions, forming a partial surface layer that attenuates the platinum XPS signal^[3].
Aminopropyltrimethoxysilane (1 mM; 5 min) rapidly adsorbs onto platinum surfaces from acidic solution within 5 min, partially blocking hydrogen adsorption/desorption and platinum oxide reduction processes^[3].
Aminopropyltrimethoxysilane (1 mM; 24 h) forms a loosely packed monolayer on the platinum surface, which only partially blocks the electron transfer of ferrocyanide/ferricyanide^[3].
Aminopropyltrimethoxysilane (10 mM; 12 h) is successfully immobilized on the surface of alkali-heat-treated AZ31B magnesium alloy via self-assembly, forming a covalently bonded silane layer containing amine groups and Si-O functional groups^[4].
