摘要
采用固体核磁共振技术CP/MAS 13C NMR分析了木质素酚醛树脂炭膜。结果显示木质素含量的变化影响到炭膜的结构,如:炭膜中侧链烷基碳、非酚型紫丁香基和羟甲基碳结构。
Carbon membrane derived from lignin-phenol-formaldehyde resin is analysed by using CP/MAS ^13C NMR spectruin technology. The results showed that the change of lignin amount influenced the structure of carbon membrane such as the structure of lateral chain alkyl carbons, non-phenol syrigyl and hydroxymethyl carbons in the carbon membrane.
