Modification of coal tar pitch ( CTP ) as carbon materials was studied using furan resin as a modifer. The modification mechanism was studied using fourier transform infra-red ( FT-IR ) and scanning electronic microscope ( SEM ) respectively. 以呋喃树脂为改性剂对煤沥青进行了改性,采用傅立叶红外光谱(FT-IR)和扫描电镜(SEM)对呋喃树脂改性煤沥青的机理进行了分析;
The modification mechanism was studied by fourier transform infra-red ( FT-IR ) and 1H nuclear magnetic resonance ( 1H-NMR ) spectroscopy technologies, respectively. 采用傅立叶红外光谱(FT-IR)和核磁共振氢谱(1H-NMR)对煤沥青改性机理进行分析;
The process of photochemical degradation was assessed by Fourier Transform infra-red ( FTIR ) spectroscopy, weight loss and hydroperoxide analysis following artificial aging. 通过FTIR、失重分析以及氢过氧化物分析表征人工加速耐老化检测中复合涂层光降解变化过程。
