a “dry” purification method can be designed to remove the byproducts, which are mainly ammonium sulfate
and aniline oligomeric salts, polyaniline will be obtained in a completely solvent-free system. The most applicable solid-state purification method for polyaniline synthesis seems to be thermal decomposition or evaporation since the byproducts can be sublimed or decomposed before the decomposition temperature of polyaniline. For example, ammonium sulfate decomposes between 230 and 280 °C, while the decomposition temperature of polyaniline is above 280 °C. In a preliminary experiment, anilinium sulfate and ammonium peroxydisulfate were first ball-milled for 1 h, transferred to a crucible, and heated at 250 °C. As a control experiment, the same amount of ammonium peroxydisulfate as used in the synthesis was placed in another crucible and heated with the polyaniline produc
The mechanochemical route to polyaniline still involves “wet” processes during the purification steps. If
a “dry” purification method can be designed to remove the byproducts, which are mainly ammonium sulfate and aniline oligomeric salts, polyaniline will be obtained in a completely solvent-free system. 用于聚苯胺的机械化学途径还涉及纯化步骤中的“湿法”过程。如果一种“干法”纯化方法可以设计成除去副产物（这主要是硫酸胺和苯胺低聚盐），那么聚苯胺就可在完全无溶剂的系统内获得。The most applicable solid-state purification method for polyaniline synthesis seems to be thermal decomposition or evaporation since the byproducts can be sublimed or decomposed before the decomposition temperature of polyaniline. 用于聚苯胺合成的，最适用的固态纯化方法似乎是热分解或脱水，因为在聚苯胺的分解温度之前，副产物就可被升华或分解。For example, ammonium sulfate decomposes between 230 and 280 °C, while the decomposition temperature of polyaniline is above 280 °C. 例如，硫酸铵在230和280 °C 之间分解，而聚苯胺的分解温度是280 °C 以上。In a preliminary experiment, anilinium sulfate and ammonium peroxydisulfate were first ball-milled for 1 h, transferred to a crucible, an
