| 摘 要： | 以硫酸为催化剂,芳基乙炔为前驱体,经聚合、正戊烷发泡、炭化获得了高强度炭泡沫。通过选择合适的制备条件,如:发泡剂的用量,催化剂的浓度及用量,以及匀泡剂吐温80的添加量,可以制得孔结构良好、韧带和接点光滑的炭泡沫。芳基乙炔聚合物泡沫炭化后高的残炭率(86%)和良好的孔结构赋予炭泡沫较高的机械强度;所制炭泡沫的耐压强度达到25.8MPa,强度/密度比为43.0MPa/(g.cm-3).

| Abstract: | Carbon foams with high mechanical strength were prepared by polymerization of arylacetylene using sulfuric acid as a catalyst,pentane as a blowing agent and Tween 80 as a bubble stabilizer,followed by carbonization. Through controlling the preparation conditions such as the proportion of blowing agent,the concentration and volume of the catalyst,and the amount of the bubble stabilizer,carbon foams with good porous structure,smooth ligaments,and junctions without microcracks could be fabricated.
