Mar 15, 2015 · Fourier transform infrared (FTIR) spectroscopy was used to probe the absorption bands of NH 2, CH 2, SiO and SiH x groups forming in APTES-Si and APTES-PS complexes. The PS samples were dipped for different periods in hydrolyzed APTES solution.

Oct 22, 2008 · Parameters important to the self-assembly of 3-(aminopropyl)triethoxysilane (APTES) on chemically grown silicon oxide (SiO 2) to form an aminopropyl silane (APS) film have been investigated using in situ infrared (IR) absorption spectroscopy.

3-aminopropyltriethoxysilane (APTES) is an organosilane molecule that is frequently used in silane-based functionalization processes that attach biomolecules to surfaces. Organosilanes are silicon-based molecules that have a general formula of R′ (CH 2)nSi (OR) 3, where R′ is an organofunctional group and R is a hydrolyzable alkoxy group [1, 2].

The bare SiO 2 (50 nm) nanoparticles modified with 3-aminopropyl (triethoxysilane), APTES@SiO 2 (50 nm), show a remarkable CO 2 sequestration enhancement compared to the pristine material (0.57 vs. 0.80 mmol/g respectively at 50 °C).

In this work, (3-aminopropyl)triethoxysilane (APTES) carrying one primary amino group was deposited on various substrate surfaces using the plasma polymerization method. The key plasma parameters...

Feb 1, 2012 · The use of the coupling agent, 3-aminopropyltriethoxysilane (APTES), in the silanization reaction with silanol-terminated silicon is an important surface modification reaction.

Jan 15, 2020 · The silanization base on APTES modification is a common method for attachment of biomolecule on silicon and silicon substrates, especially Si 3 N 4 surface. Consequently, the effect of APTES concentration and reaction time which are the key parameter for APTES modification were studied.

This paper reports the development and characterization of nano-hybrid coatings using tetraglycidyl 2,2-bis(4-(4-amine phenoxy)phenyl)propane (TGBAPPP) and 3-aminopropyltriethoxysilane (APTES ...

Attenuated total reflectance infrared spectroscopy (ATR-IR) was used to study the dynamic layer-by-layer (LBL) growth of sodium polyacrylate (NaPA)/poly(diallydimethylammonium) chloride...

In this paper we report detailed Fourier transform infra-red (FTIR) and Raman spectroscopic results obtained after the modification of a porous silica surface using different steps of functionalization and protein grafting.
