Horseradish peroxidase isoenzyme C (HRPC) is often used as catalyst for the preparation of the conductive emeraldine salt form of polyaniline (PANI-ES) from aniline and hydrogen peroxide (HO) in the presence of anionic templates in aqueous solution. Here, a direct comparison of three types of soft templates was made, (i) the sodium salt of sulfonated polystyrene (SPS), (ii) micelles from sodium dodecylbenzenesulfonate (SDBS), and (iii) vesicles from either a 1 : 1 molar mixture of SDBS and decanoic acid or from AOT (sodium bis(2-ethylhexyl)sulfosuccinate). Based on UV/vis/NIR, EPR and Raman spectroscopy measurements all three types of templates are similarly suitable, with advantages of the two vesicle systems in terms of aniline conversion degree and radical content in the final PANI-ES product. First experiments with sulfated cellulose nanocrystals (CNCs) indicate that they are promising rigid templates for the preparation of electroconductive PANI-ES-coated cellulose materials or devices.
辣根过氧化物酶同工酶C（HRPC）常被用作催化剂，在水溶液中于阴离子模板存在的情况下，由苯胺和过氧化氢（HO）制备聚苯胺的导电翡翠盐形式（PANI-ES）。在此，对三种类型的软模板进行了直接比较：（i）磺化聚苯乙烯（SPS）的钠盐，（ii）十二烷基苯磺酸钠（SDBS）形成的胶束，以及（iii）由SDBS与癸酸的1:1摩尔混合物或由AOT（双（2-乙基己基）磺基琥珀酸钠）形成的囊泡。基于紫外/可见/近红外、电子顺磁共振和拉曼光谱测量，所有三种类型的模板都同样适用，两种囊泡体系在苯胺转化率和最终PANI-ES产物中的自由基含量方面具有优势。对硫酸化纤维素纳米晶体（CNCs）的初步实验表明，它们是制备导电PANI-ES包覆纤维素材料或器件的有前景的刚性模板。
