In order to improve the surface hydrophobicity, silicone rubber (SIR) samples were exposed to CF4 radio frequency (RF) capacitively coupled plasma (CCP). Attenuated total reflection Fourier transform infrared (ATR-FTIR) spectrum and X-ray photoelectron spectroscopy (XPS) were used to observe the ...
The three peaks at 472, 804, and 1109 cm−1 changed compared with the FTIR spectrum of untreated fillers. The new peak appeared at 1620 cm−1 after chemical treatment with silane coupling agent. The two peaks at 472 and 804 cm−1 are assigned to the Si–O bond, whereas the two ...
Surface chemical composition were analyzed by X-ray photoelectron spectroscopy (XPS) and attenuated total reflection Fourier transform infrared (ATR-FTIR) spectrum, and atom force microscope (AFM) was employed to observe the surface topography, and static contact angle (SCA) measurement was performed ...
Si – O – Si, Si – (CH3)2, and Si – CH3 bonds are the primary bonds in the silicone oil with higher intensities in the FTIR spectrum. Silicon and oxygen have a chance to connect with H when the primary bonds are broken. Decreasing the intensities of the Si – O, and Si – ...
Fig. 2: FTIR spectrum identifies constituents of silicone polymer. Additional physico-chemical parameters (outlined in Fig. 3) should also be considered with the goal of establishing reference properties of the silicone used in a coating intended for electrical applications. ...
Fourier Transform Infrared (FTIR) spectra were collected on a PERKIN-ELMER Spectrum 400 FT-IR/FT-NIR spectrometer fitted with a universal Attenuated Total Reflectance (ATR) sampling accessory. All refractive indices were collected on a Milton Roy model 33.46.10 ABBE Refractometer at 20° C....
Cerium (Ce)-ferric (Fe) complex oxides were prepared via a citric acid sol-gel process, and used as thermal oxidative stabilizers for silicone rubber (SR). The oxides were characterized by X-ray diffraction and Raman spectroscopy. The Ce/Fe molar ratio in Ce-Fe complex oxides significantly ...
“silicone” may be used interchangeably with polyorganosiloxane or may describe a specific compound, such as a silicone rubber, e.g. that may or may not be curable. The silicone encapsulant includes the additive and also a silicone, a polyorganosiloxane, or a polyorganosiloxane composition ...
components are typically allowed to react until at least 95 mol %, alternatively at least 98 mol %, alternatively at least 99 mol %, of the silicon-bonded hydrogen atoms originally present in the silicone rubber have been consumed in the hydrosilylation reaction, as determined by FTIR ...
