Aminopropyltriethoxy silane

Principally, the main differentiation for uniform monolayers made by silanization is whether they are formed from long-chain or short-chain organosUanes. For long-chain silanes, a number of alkyltrichlorosilanes is described in the literature (for example l-thioacetato-16-(trichlorosilyl)-hexadekane [19]), and for silanization with short-chain compounds several different alkyltrialkoxysilanes are used (for example 3-aminopropyltriethoxy-silane, APTES). 

Modeling calculations of electronic and molecular parameters and thermodynamic functions of 1-aminopropyltriethoxysilane (II), 2-aminopropyltriethoxysilane (III), and 3-aminopropyltriethoxy-silane (la), which had a different position of the N atom in respect to Si, were performed by computer chemistry methods (Gaussian 98, HyperChem 6.0 software).

Functionalization. MS fimctionalization was performed by addition of 3-aminopropyltriethoxy-silane to a suspension of organic firee MS in refluxing toluene and stirred for 5 h. The solid (MS-F) was filtered, washed in a Soxhlet apparatus with diethylether and dichloromethane and dried at 120 °C [6]. 

It has also been shown that a self-assembled monolayer (SAM) with proper functional groups can significantly improve the adhesion of CP thin film on a substrate. Based on this concept, Jung and Lee have demonstrated the fabrication of CP nanostmctures via a lift-off process. In their study, 16-mercaptohexadecanolc acid and 3-aminopropyltriethoxy silane SAM were used on Au and Si02/Si surfaces to promote the adhesion of PPY and PEDOT PSS, respectively. This allowed nanostmctures of these CP materials to be fabricated using standard e-beam lithography followed by a lift-off process [14].

In this study, mesoporous silica, SBA-15, was synftiesized using a sol-gel method. Three different types of metal catalysts were prepared via the silylation and grafting techniques, hr particular, Ni-L-SB A was prepared by the impregnation with UX-984 after silanization by 3-aminopropyltriethoxy silane (APTES, Aldrich Giemical Co.) of the SBA-15 and Ni-L-CS was prepared using a conventional silica as a siqrport. Ni-E-SBA was synthesized by the...

The fabrication of PVA/titanium dioxide nanocomposites with different titanium dioxide (Ti02) loading by using ultrasoxmd irradiation has been described (157). For an improvement of the dispersion of the nanoparticles and for increasing possible interactions between nanoparticles and PVA, the surface of Ti02 nanoparticles was modified by y-aminopropyltriethoxy silane.
