Electrically conductive cotton fabric was fabricated by in situ one pot oxidative polymerization of aniline. Using a simple heterogeneous polymerization method, polyaniline (PANI) nano fibers with an average fiber diameter of 40–75 nm were grafted in situ onto cotton fabric. The electrical conductivity of the PANI nanofiber grafted fabric was improved 10 fold compared to fabric grafted with PANI nanoclusters having an average cluster size of 145–315 nm. The surface morphology of the cotton fibers was characterized using SEM and AFM. Electrical conductivity of PANI nanofibers on the cotton textile was further improved from 76 kΏ/cm to 1 kΏ/cm by increasing the HCl concentration from 1 M to 3 M in the polymerization medium. PANI grafted cotton fabrics were analyzed using FTIR, and the data showed the presence of polyaniline functional groups on the treated fabric. Further evidence was present for the chemical interaction of PANI with cellulose. Dopant level and morphology dependent electron transition behavior of PANI nanostructures grafted on cotton fabric was further characterized using UV–vis spectroscopy. The electrical conductivity of the PANI nano fiber grafted cotton fabric can be tuned by immersing the fabric in pH 2 and pH 6 solutions for multiple cycles.

导电棉织物是通过原位一锅法苯胺氧化聚合制备的。使用简单的非均相聚合方法，将原位接枝平均纤维直径为40-75 nm的聚苯胺（PANI）纳米纤维在棉织物上。与用平均簇尺寸为145-315 nm的PANI纳米簇接枝的织物相比，PANI纳米纤维接枝的织物的电导率提高了10倍。使用SEM和AFM表征棉纤维的表面形态。通过将聚合介质中的HCl浓度从1 M增加到3 M，PANI纳米纤维在棉织物上的电导率从76kΏ/ cm进一步提高到1kΏ/ cm。使用FTIR对PANI接枝的棉织物进行了分析，数据表明在处理过的织物上存在聚苯胺官能团。有关PANI与纤维素的化学相互作用的进一步证据。紫外可见光谱进一步表征了嫁接在棉织物上的PANI纳米结构的掺杂水平和形貌相关的电子跃迁行为。PANI纳米纤维接枝棉织物的电导率可以通过将织物浸入pH 2和pH 6溶液中多个周期来进行调节。
