The structural and optical properties of technologically interesting pyrolytic carbons formed from cured novolac resin and cured novolac/biomass composites were studied by X-Ray Diffraction Analysis (XRD), and Fourier Transform Infrared (FTIR), Raman and Photoluminescence (PL) spectroscopy. Pyrolysis of the cured materials took place at temperatures in the range 400-1000 degrees C. The most important weight loss, shrinkage and structural changes of pyrolyzed composites are observed at temperatures up to 600 degrees C due to the olive stone component. In the same temperature range, the changes in pyrolyzed novolac are smaller. The spectroscopic analysis shows that novolac pyrolyzed up to 900 ( degrees )C has less defects and disorder than the composites. However, above 900 ( degrees )C, pyrolyzed novolac becomes more disordered compared to the pyrolyzed composites. It is concluded that partial replacement of novolac by olive stone in the composite materials leads to the formation of a low cost, good quality product.
通过X射线衍射分析（XRD）、傅里叶变换红外光谱（FTIR）、拉曼光谱和光致发光（PL）光谱，研究了由固化酚醛清漆树脂以及固化酚醛清漆/生物质复合材料形成的具有技术意义的热解碳的结构和光学性质。固化材料在400-1000摄氏度范围内进行热解。由于橄榄石成分，在高达600摄氏度的温度下观察到热解复合材料最重要的失重、收缩和结构变化。在相同温度范围内，热解酚醛清漆的变化较小。光谱分析表明，热解至900摄氏度的酚醛清漆比复合材料具有更少的缺陷和无序度。然而，在900摄氏度以上，与热解复合材料相比，热解酚醛清漆变得更加无序。得出的结论是，在复合材料中用橄榄石部分替代酚醛清漆会导致形成低成本、高质量的产品。
