Chemically reinforced polyethylene is used in many industrial applications. Fluorination of the polyethylene surface is one of the processes for improving its performance. However, to obtain the specified material, thefluorination level must be monitoredto ensure correct measurements. An FT-IR spectrometer...
Using FT-IR spectra, the quantitative determination of the different functional groups has also been carried out. While the initiation and termination steps are common to all PTC oxidations of low density polyethylene, the propagation in the tetrabutyl ammonium bromide (TBAB)-catalysed process occurs ...
consortia [43]. Similarly, Harshvardhan and Jha [42] reported PE biodegradation with an increase in the index of carbonyl bond, the keto carbonyl bond, and the vinyl bond, calculated using FT-IR spectra. These functional groups at the surface of PE are considered important because oxidized ...
采用扫描电子显微镜(SEM)、傅里叶变换红外光谱仪(FT-IR)、差示扫描量热仪(DSC)、热重分析仪(TG)等技术考察了PEG/EC复合相变蓄热材料的微观形貌、相容性及化学结构、蓄热性能及稳定性.结果表明,PEG/EC复合相变材料为不规则颗粒状粉末,PEG与EC的相容性较好,分子间形成氢键而没有形成新的化学键.由于EC与PEG间...
IR analysis (identification of carbonyl groups in polyethylene): measurement in conditions including wave-number resolution of 4 cm-1, 64 scans, and sample thickness of about 1 mm, using Series-1600 FT-IR from Perkin-Elmer Co., Ltd., and determination of the presence of peaks and absorbance...
