Abstract
Polyamic acid (PAA) nanofibers produced by using the electrospinning method were fully
characterized in terms of morphology and spectroscopy. A PAA nanofiber–modified
screen-printed carbon electrode was applied to the detection of selected sulfonamides
by following an electroanalytical protocol. The polyamic acid (PAA) nanofibers were
characterized using Fourier transform infrared (FTIR) spectroscopy to study the
integrity of polyamic acid functional groups as nanofibers by comparing them to
chemically synthesized polyamic acid. A scanning electron microscope (SEM) was
used to confirm the morphology of the produced nanofibers and 3D arrangement at
the electrode interface. The Brunauer–Emmett–Teller (BET) method was used to
determine the surface area of the nanofibers. Atomic force microscopy (AFM) was
used to study the porosity and surface roughness of the nanofibers.
