“…The stretching vibrations of ethylene oxide at 1180, 1049, and 1288 cm −1 contribute to the C-O-C stretching vibration. The characteristic peaks at 1301 and 1501 cm −1 are attributed to the stretching vibrations of C=C and C-C on the selenophene ring in the PEDOS [ 25 ].…”

To solve the problem that zinc oxide nanorods (ZnO NRs)-based self-powered ultraviolet (UV) photodetectors cannot obtain both higher responsiveness and shorter response time, P(EDOS-TTh) was prepared using 3,4-ethylenedioxyselenphene (EDOS) and terthiophene (TTh) as copolymers, which modify the ZnO NRs surface, and the ZnO/P(EDOS-TTh) P-N junction self-powered UV device is assembled. The effect of the number of electrochemical polymerization cycles on the UV photodetection performance of ZnO/P(EDOS-TTh) P-N heterojunction was studied by adjusting the number of electrochemical polymerization cycles at the monomer molar ratio of 1:1. Benefiting from the enhanced built-in electric field of the ZnO/P(EDOS-TTh) interface, balancing photogenerated carriers, and charge separation and transport. The results show that the contact between N-type ZnO NRs and P-type P(EDOS-TTh) is best when the number of polymerization cycles is 3, due to the fact that EDOS-TTh and ZnO NRs form excellent P-N heterojunctions with strong internal electric fields, and the devices show good pyroelectric effect and UV photodetection performance. Under 0 V bias and 0.32 mW/cm2 UV irradiation, the responsivity (R) of ZnO/P(EDOS-TTh) reaches 3.31 mA/W, the detectivity (D*) is 7.25 × 1010 Jones, and the response time is significantly shortened. The rise time is 0.086 s, which exhibited excellent photoelectric properties and stability. UV photodetection performance with high sensitivity and fast response time is achieved.

Growing environmental and health demands along with the deficiency of conventional energy sources result in the need for alternative solutions in the field of energy storage and analyte detecting systems. To address these issues, a significant increase in research interest for novel composite materials has been observed in recent years. Conductive polymers and graphene‐based composites have emerged as promising electrode materials for supercapacitors and electrochemical sensors due to their improved electrochemical properties and versatility of the synthesis methods. The synergistic effect between the composite components and the unique morphology, physical and chemical characteristics result in enhanced performance of the electrochemical devices. In this review, we discuss recent trends and achievements in the synthesis, nanoarchitecture, and application of conductive polymers and graphene‐based composites in the field of supercapacitors and electrochemical sensors. Finally, the remaining challenges and future perspectives are discussed. It is believed that this review will provide a current summary and new inspiration for groundbreaking research on advanced electrochemical devices.

“…Reproducibility of the sensor has been proven by the obtained 2.69% percentage of the relative standard deviation (RSD) of DA currently obtained with six independent NG/PEDOT/GCEs under the same conditions. Another group investigated the association of graphene with poly(3,4-ethylenedioxyselenophene) (PEDOS) and nitrogen-doped graphene (N-Gr) and compared the PEDOS/N-Gr composite with poly(3,4-ethylenedioxythiophene) (PEDOT)/nitrogen-doped graphene (PEDOT/N-Gr) for dopamine detection [71]. They showed that the composite formed with PEDOS has an enhanced analytical performance compared to the PEDOT composite.…”

Graphene and its derivatives have been widely used for the electrochemical detection of dopamine (DA) neurotransmitter, thanks to its high surface area and excellent conductivity. Modified graphene and graphene-based nanocomposites have shown improved catalytic activity towards DA detection. Various modification approaches have been taken, including heteroatom doping and association with other nanomaterials. This review summarizes and highlights the recent advances in graphene-based electrodes for the electrochemical detection of DA. It also aims to provide an overview of the advantages of using polymer as a linker platform to form graphene-based nanocomposites applied to electrochemical DA sensors.
