Structural Features of Surface Layers of Bifunctional Polysiloxane Xerogels Containing 3-Aminopropyl Groups and 3-Mercaptopropyl Groups
Polysiloxane xerogels containing both –SH and –NH 2 functions have been prepared using the sol–gel method with alkoxysilane precursors [such as Si(OEt) 4 , (MeO) 3 Si(CH 2 ) 3 SH and (EtO) 3 Si(CH 2 ) 3 NH 2 ]. Molar ratios of 3.2:1, 1.1:1 and 0.4:1 for the two functions –SH and –NH 2 were employed....
