The characteristics of the AP include (1) in addition to the formation of hydrogel in aqueous alkaline or polar organic solution, AP can form carbonaceous hydrogel in neutral and acidic aqueous solutions, which extents the application of carbonaceous sol-gel;(2) AP contains a large amount of nitric groups which decomposes quickly by thermal initiation, releasing a large amount of gases and heat, indicating explosive properties of the AP;(3) metal salt-containing AP is also explosible by thermal initiation, and the metal in AP promotes the explosion.

以沥青为碳源,用氧化法制备水性沥青过程中,浓硫酸和浓硝酸的比例、用量、氧化温度及氧化时间对水性沥青的收率皆有影响。经过氧化后,沥青上含有许多含氧官能团,导致水性沥青溶于水。含氧官能团越多,水性沥青越易溶于水。调节制备条件,可使水性沥青不仅可以在碱性水溶液中形成凝胶,而且可以在中性和酸性水溶液中形成溶胶、凝胶,从而拓宽了炭基溶胶—凝胶法制备炭基纳米材料的应用范围。
