A new route for the preparation of flexible skin–core poly(ethylene-co-acrylic acid)/polyaniline functional hybrids

Synthesis and characterization of conductive polyaniline nanocomposite containing fluorene

Fluorene, an excellent electroluminescent material, has been used as a core to synthesize a core–shell fluorene/polyaniline (fluorene/PANI) composite using ammonium persulfate as an oxidant. The influence of the fluorene–aniline molar ratio and the oxidant–aniline molar ratio on the resistance of the composite was investigated, and the crystallinity, structure, and morphology of the fluorene/PANI composite were characterized by X-ray diffraction, Fourier transform infrared spectroscopy, and scanning electron microscopy. The results indicate that the fluorene/PANI composite has a core–shell structure and exhibits good conductivity. A more planar conformation of PANI could be formed because of strong π–π interactions between the fluorene core and the PANI shell.

Electrical Switchability and Dry-Wash Durability of Conductive Textiles

There is growing interest in the area of conductive textiles in the scientific and industrial community. Herein, we successfully prepared a conductive textile via covalently grafting polyaniline (PANI) onto cotton by a multi-step treatment process. The conductivity of the resultant fabric could be tuned by immersing in water having different pH values. The conductive and insulating properties of the textile could be conveniently switched by alternately immersing in acidic and alkaline bath solutions. Most importantly, the resultant conductive fabrics were able to withstand 40 simulated dry-wash cycles, with almost no decay in the electrical conductivity, indicating their excellent dry-wash durability. The present strategy for fabricating conductive fabrics with excellent switchability of electrical properties and dry-wash durability is expected to provide inspiration for the production of multifunctional conductive textiles for use in hash or sensitive conditions.
