Morphological control of conductive polymers based on node number control

导电聚合物是制造电子电路的有力竞争者。研究了电聚合法合成导电聚合物的生长规律。这种生长模式与自由基阳离子的偶联反应和随后的去质子化反应密切相关，并随支持电解质和所用溶剂的种类和浓度的不同而突然改变。也就是说，当亲电取代偶联反应占优势时，观察到三维生长形态，当自由基偶联反应占优势时，观察到二维生长形态。此外，通过改变聚合恒流值可以比较容易地控制生长模式，为利用共轭聚合物制成的神经元型器件的生物电路研究提供了指示和发展。

Conductive polymers are a strong contender for making electronic circuits. The growth pattern in conductive polymer synthesis by the electrolysis polymerization method was examined. The growth pattern is deeply related to the coupling reaction of the radical cation and the deprotonation reaction following it, and changes suddenly depending on the kind and concentration of the supporting electrolyte and the solvent used. That is, when the electrophilic substitution coupling reaction becomes predominant, the three-dimensional growth form is observed and when the radical coupling reaction becomes predominant, the two-dimensional growth morphology is observed. In addition, the growth pattern can be comparatively easily controlled by changing the value of the polymerization constant current, and it is considered that the indicator and development for biocircuit research with neuron-type devices made of conjugated polymers was obtained.
