Abstract
We present the first fast and facile microwave assisted synthesis of polyaniline (PANI) nanofibers ("MWA synthesis"). Under conventional synthesis (CS), the polymer was produced with 79.7% yield after 5 h at ambient temperature. However, under microwave irradiation, the nanofibers were produced with yield of 76.2% after only 5 min, i.e., with 78.8% after 20 min at ambient temperature. The FTIR and Raman spectra show the PANI structure in all samples either synthesized conventionally or in the microwave. SEM and TEM confirm the nanofibrillar morphology.

Main findings
Microwave-assisted synthesis produced polyaniline nanofibers with 76.2% yield after 5 minutes (and 78.8% after 20 minutes), compared with 79.7% yield after 5 hours under conventional synthesis. FTIR and Raman spectra indicated PANI structure in all samples, and SEM/TEM confirmed nanofibrillar morphology.
Outcomes measured
- Polyaniline (PANI) nanofiber synthesis yield
- FTIR spectra characterization

- SEM morphology
- TEM morphology
Limitations
- No microwave frequency, power, or dosimetry (e.g., SAR) reported in the abstract
- No sample size or replication details provided in the abstract
- Outcomes are materials synthesis/characterization rather than biological or health endpoints
