Structural, morphological and sensing properties of layered polyaniline nanosheets towards hazardous phenol chemical

► Novel layered PANI nanosheets are prepared by the chemical polymerization. ► layered PANI nanosheets utilize as working electrode for highly sensitive phenol chemical sensor. ► Raman mapping confirms the formation of high quality of layered PANI nanosheets. ► Fabricated phenol chemical sensor shows a very high sensitivity of ∼1485.3 μA mM−1 cm−2.
