- Abstract
In the present work, we have prepared polymer blend of polyvinyl butyral (PVB) and poly(3,4‐ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) by solution casting route. Blends were tested for various structural, morphological, and electrochemical techniques. Structural properties were investigated by XRD technique exploring the contribution conducting polymer in host system PVB exhibit amorphous nature. COO functional group contributed in blend configuration was confirmed by FTIR technique. Clustering of PEDOT:PSS in blend system were observed by scanning electron microscopy. Subatomic surface topology and increased roughness due to blending concentration of conducting polymer were analyzed by probe microscopy techniques. Increased softness of blends was confirmed by shore "A" durometer test. PVB/PEDOT:PSS blend was drop casted on glassy carbon electrode and employed for detection of various metal ions. It was deployed for electrochemical sensing of Cu2+ ion. Electrochemical sensing investigation was done by differential pulse voltammetry technique. Performance of blends at 4.5 pH, 200 s deposition time and −1.2 V deposition potential was more accurate and sensitive toward detection of Cu2+ ion. The developed electrochemical sensor exhibited rapid sensing response in the range of 1.6 to 8.3 μm. Furthermor,e an influence of many analytical parameters such as pH, deposition time and deposition potential on Cu2+ ion investigation were disclosed. This investigation may be feasible to construct a very simple, fast, and efficient electrochemical sensing system for toxic heavy metals at low‐level concentration.
