Abstract
Polyaniline (PANI) composite microwires containing CdS nanoparticles were synthesized guidedby poly(acrylic acid) (PAA). It was found that the morphology of the composite microwireswas affected by the concentration of PAA. When the concentration of PAA was lower than0.1 mg ml−1, the PANI/CdS composite was wires. However, no wire-like structures ofPANI/CdS composites were formed when the concentration of PAA was higher than1.0 mg ml−1. The complex of CdS nanoparticles with PANI matrix was affected by the molar ratio ofCdS to aniline. When the molar ratio was 1:75, CdS nanoparticles were well combined withPANI matrix. However, when the molar ratio was 1:150, no CdS nanoparticles werecombined with PANI wires. SEM, TEM, FTIR and XRD characterized the PANI/CdScomposite microwires and proved that the CdS nanoparticles are combined with the PANImatrix in some conditions, and TEM proved that some of the microwires are in fact ofhelical shape. The photoluminescence of CdS is slightly affected by its combination withthe PANI matrix.
