The pendent thiol group grafed poly(3,4-proplenedioxythiophene) hollow nanofiber for electrochemical sensing

Using CTAB as surfactant in CHCl3 system, a uniform PProDOT-(MeSH)2 hollow nanofibers are formed. The strong non-covalent bond and π-π stacking between thiol groups in polymers and drug molecules contribute to improvement of electrochemical sensing of PAR. It provides a new idea and method for the preparation of polymer hollow nanofibers and electrochemical sensing. [Display omitted] •A new method is proposed to prepare polymer hollow nanofibers for electrochemical sensing.•PProDOT-(MeSH)2 hollow nanofibers are formed using CTAB as surfactant.•The hollow nanofiberous structure and thiol groups are beneficial to improve the electrocatalytic performance. The pendent thiol group grafed poly(3,4-proplenedioxythiophene) (PProDOT-(MeSH)2) hollow nanofibers (HNFs) were prepared via surfactant-assisted method of cetyltrimethyl ammonium bromide (CTAB), and the influence of CTAB concentration on the morphology and electrochemical performance of PProDOT-(MeSH)2 were investigated. The physical and chemical properties of PProDOT-(MeSH)2 HNFs were studied by FT-IR, UV–vis, XRD, SEM, TEM and the electrocatalytic activity were evaluated by detecting paracetamol using differential pulse voltammetry (DPV) techniques. The results showed that the PProDOT-(MeSH)2 HNFs in 0.009 M CTAB exhibited a much better electrocatalytic performance.
