可打印原料可以生产轻质、坚固、延展性好且具有可调节和可切换电导率的结构，受到众多应用领域的广泛关注。将商品热塑性塑料的特定性能与导电聚合物 (CP) 独特的电学和氧化还原性能相结合，为印刷（生物）电子领域带来了新的机遇。在此，我们报告了基于聚苯胺-二壬基萘磺酸 (PANI-DNNSA) 的油墨配方的直接油墨写入 (DIW) 印刷，该油墨配方已大批量合成（约 400 克）。 DNNSA 赋予 PANI 高达 50 mg mL(-1) 的溶解度，允许使用各种添加剂来调节油墨的流变行为，而不会显着影响印刷结构的电性能，其电导率范围为
Printable feedstocks that can produce lightweight, robust, and ductile structures with tunable and switchable conductivity are of considerable interest for numerous application spaces. Combining the specific properties of commodity thermoplastics with the unique electrical and redox properties of conducting polymers (CPs) presents new opportunities for the field of printed (bio)electronics. Here, we report on the direct ink write (DIW) printing of ink formulations based on polyaniline-dinonylnaphthalene sulfonic acid (PANI-DNNSA), which has been synthesized in bulk quantities (similar to 400 g). DNNSA imparts solubility to PANI up to 50 mg mL(-1), which allows the use of various additives to tune the rheological behavior of the inks without significantly compromising the electrical properties of the printed structures, which reach conductivities in the range of
