Although the diameter of conductive polymer nanoparticles can be controlled effectively, the uniformity of particle length is still very challenging. In this study, with the temperature‐sensitive block copolymer PS₁₁₁‐b‐PNIPAM₁₁₄ as the template, the morphology and size of polyaniline (PANI) particles had been controllably adjusted through the change of temperature. Additionally, the electrochemical performance of each sample was investigated. After PS₁₁₁‐b‐PNIPAM₁₁₄ was synthesized through the reversible addition‐fragmentation chain transfer radical polymerization (RAFT), with its vesicular micelle as the “template”, the PANI particles with uniform length distribution were prepared successfully at 40°C. The average length of PANI particles after template removal was 254.07 nm with a short tail distribution, which was closer to the average than the standard normal distribution. Electrochemical results of PANI showed that it had good electrochemical activity with fast charge and discharge ability. And, with the current density of 1 A·g⁻¹, its discharge‐specific capacitance could reach up to 805.61 F·g⁻¹.

以热敏嵌段共聚物为模板的聚苯胺颗粒的可控长度调节

尽管可以有效地控制导电聚合物纳米颗粒的直径，但是颗粒长度的均匀性仍然非常具有挑战性。在这项研究中，以温度敏感的嵌段共聚物PS ₁₁₁ - b- PNIPAM ₁₁₄为模板，通过温度变化可控地调节了聚苯胺（PANI）颗粒的形貌和尺寸。另外，研究了每个样品的电化学性能。在PS ₁₁₁ - b- PNIPAM _114之后通过可逆加成-断裂链转移自由基聚合（RAFT）合成，以其囊泡胶束为“模板”，在40°C成功制备出长度分布均匀的PANI颗粒。模板去除后，PANI颗粒的平均长度为254.07 nm，具有短尾巴分布，比标准正态分布更接近平均值。PANI的电化学结果表明，它具有良好的电化学活性，具有快速的充放电能力。并且，当电流密度为1 A·g ^-1时，其放电比电容可达到805.61 F·g ^-1。
