- Abstract
Conjugated polymer nanofibers with lengths of tens of micrometers and diameters of hundreds of nanometers are prepared via the assembly of polypyrrole (PPy) nanoparticles in water using a freeze-drying method. The structure and uniformity of the PPy nanofibers are critically affected by the processing conditions, such as the freezing temperature and the concentration of the latex dispersion. These nanofibers are subsequently applied as vapor sensors for efficient detection of organic explosive chemicals.
