Abstract
Conductive polyaniline (PANI)-based textiles are developed using a heterocoagulation-controlled deposition mechanism. In contrast to conventional in situ polymerization, this approach exploits the interaction between oppositely charged PANI particles and textile substrates to form specialized percolation networks. Polyamide substrates form highly interconnected networks with excellent conductivity, while cotton nonwovens exhibit less regular pathways. The heterocoagulation approach allows for fine-tuning of the layer structure, lowers the percolation threshold, achieves high conductivity while maintaining textile flexibility, and enhances durability against washing, dry, and wet rubbing. This methodology presents a systematic approach for controlling the structure–property–percolation relationship in conductive textiles, enabling potential applications in sensors, antistatic fabrics, and flexible electronics.
