摘要: 測試分析了碳化處理條件對酚醛樹脂碳化產物組成和結構的影響.實驗結果發現酚醛樹脂620℃碳化處理后的樣品已開始出現微弱的(100)晶面衍射峰,表明已產生了一些石墨微晶,但1 000℃處理的酚醛樹脂碳化產物石墨化程度還較低,仍屬于無定形碳范圍.實驗結果表明:樹脂碳化產物中各元素的質量分數均隨著碳化處理溫度升高呈現規律性變化,其中碳隨著碳化處理溫度升高而增大, 氫、氧則下降;在相同碳化條件下氫比氧有著更強的脫出能力.碳化處理溫度和氣氛對樹脂碳化產物的比表面積都有著較強的影響,而氣氛的影響表現得更為強烈.Abstract: The phenolic aldehyde were synthesized and then were carbonized to make carbon materials of the resin. The elements and structure of carbon materials of the resin were analyzed. The results found that the carbon materials of the resin treated at 620℃ have weekly appeared (100) crystal plane diffraction peak, it means that some graphite crystallite have produced. But the graphitization degree of the carbon materials of the resin treated at 1000℃ is still lower, and it is belong to the range of amorphous carbon. All the elementary mass fraction of the carbon materials of the resin are regularly changed with the treatment temperature increase, thereinto carbon content is accretion, hydrogen and oxygen contents are decline. The disengage speed of hydrogen is higher than that of oxygen in the same carbonization condition. Both temperature and ambience are all the factor of effect on the specific surface of the carbon materials, and the effect of ambience is more intensity.
