摘要
从光热应用的角度出发,以木糖和葡萄糖为碳源,乙酸为催化剂,通过水热法制备碳微球,采用扫描电镜、红外光谱仪、紫外-可见分光光度计、X射线衍射仪、拉曼光谱仪、自制光热性能测试装置等对碳微球结构和性能进行表征。结果表明,木糖和葡萄糖在200℃的水热条件下反应4 h可以生成表面光滑、粒径较均匀的碳微球,在相同的炭化条件下,木糖基碳微球的芳香化程度、石墨化程度高于葡萄糖基碳微球,从而使其具有更优的吸光发热性能,在吸光发热纺织品领域表现出良好的应用前景。
From the perspective of photothermal application,carbon microspheres were prepared by hydrothermal method with xylose and glucose as carbon sources and acetic acid as catalyst.The structure and properties of carbon microspheres were characterized by scanning electron microscopy,infrared spectrometer,UV-visible spectrophotometer,X-ray diffractometer,Raman spectrometer and self-made photothermal performance testing equipment.The results show that xylose and glucose can turn into carbon microspheres that have smooth surface and uniform size under hydrothermal conditions of 200 C for 4 h.Under the same carbonization conditions,the degree of aromatization and graphitization of xylose-based carbon microspheres is higher than that of glucose-based carbon microspheres,which makes them have better light absorption and heating properties,showing a good application prospect in the field of light absorption and heatingtextiles.
