Fourier transform infrared (FTIR) measurement was performed on a Perkin–Elmer FTIR 1725X spectrometer in the mid-infrared range from 400 to 4000 cm−1 with an increment of 1 cm−1 to explore the Si-H bonding configura- tions and extract hydrogen content in the films. References 1...
Si-OH、SiO2存在于硅及硅复合材料的表面,对硅及其复合材料的性能具有很大的影响。例如Si-OH存在于多孔硅的表面,对多孔硅的发光性能、多孔硅表面吸附爆炸等具有重要的意义;在硅器件中,硅片表面被氧化形成SiO2影响硅片表面薄膜的沉积,进而影响器件的性能。由于物质的微观结构决定了其各种物理化学性质,因此对硅及硅复合材...
Preliminary studies of the polymer-to-ceramic conversion process in N2 by GPC, TGA, FTIR and NMR methods indicate that cross-linking occurs by H2 elimination and Si-Si bond formation and that the 1000 °C product has a much lower proportion of free carbon than the corresponding ceramic ...
Fourier transform infrared spectroscopy (FTIR). FTIR (IR Prestige-21, Shimadzu) was extensively used for the identification of functional groups. Figure 2a exhibits Zinc aluminosilicate having broad transmis- sion band at 3,450 cm−1 attributed to OH due to absorbed water molecules and ...
