In this study, the poly(3,4-propylenedioxythiophene)/ SnO 2 nanocomposites (PProDOT/SnO 2 ) with different contents of SnO 2 were successfully prepared by using hand grinding and ball milling methods, respectively. The effects of the synthesis methods and SnO 2 on the structure and electrochemical properties of the nanocomposites were deeply discussed. The results showed the structure of composites were highly affected by the increasing amount of nano-SnO 2 particles in reaction medium of hand grinding method than ball milling method. And, the PProDOT/SnO 2 nanocomposites from ball milling method displayed similar absorption spectra, and ball milling method promoted the uniform distribution of nano-SnO 2 particles in PProDOT matrix. However, PProDOT/SnO 2 nanocomposites from hand grinding method displayed the higher specific surface area and stronger synergetic effects between PProDOT and SnO 2 than that of PProDOT/SnO 2 nanocomposites from ball milling method. As a result, the PProDOT/SnO 2 nanocomposites from hand grinding method showed higher electrochemical activity than PProDOT/SnO 2 nanocomposites from ball milling method. Moreover, the specific capacitance and cycle stability of PProDOT/SnO 2 nanocomposites from both methods were higher than respective pure PProDOT. Among all the nanocomposites, PProDOT/15wt%SnO 2 nanocomposite from hand grinding method possessed the highest specific capacitance (259 F g 21

Non-stoichiometric SiO based materials have gained much attention as high capacity lithium storage materials. However, their anode performance of these materials should be further improved for their commercial success. A conductive polymer, poly(3,4-ethylenedioxythiophene):poly(4-styrenesulfonate) (PEDOT:PSS), is employed as a flexible electrical interconnector to improve the electrochemical performance of Si/SiO nanosphere anode materials for lithium ion batteries (LIBs). The resulting Si/SiO -PEDOT:PSS core-shell structured material with the small amount (1 wt %) of PEDOT:PSS shows the improved initial reversible capacity of 968.2 mA h g with excellent long-term cycle performance over 200 cycles. These promising properties can be attributed to the use of the electroconductive and flexible PEDOT:PSS shell layer, which protects the electrical conduction pathways in the electrode from the large volume changes of silicon during cycling.

“…9,10 In addition, this work demonstrates that the anode using the conducting polymer poly(3,4-ethylene-dioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) is especially suitable for UV photodetectors owing to its high transmittance in the UV region, and it has excellent electrode properties such as high electrical conductivity, solution processability, and good stability in elevated temperature. [16][17][18] In this paper, we fabricated the high performance ZnO NFs/PVK hybrid UV photovoltaic detector. The optical, electrical, and photoelectrical properties of ZnO NFs/PVK as a photodetector have been systematically investigated to uncover the underlying mechanism of the strong photoresponse.…”

A high performance ultraviolet (UV) photodetector is receiving increasing attention due to its significant applications in fire warning, environmental monitoring, scientific research, astronomical observation, etc. The enhancement in performance of the UV photodetector has been impeded by lacking of a high-efficiency heterojunction in which UV photons can efficiently convert into charges. In this work, the high performance UV photodetectors have been realized by utilizing organic/inorganic heterojunctions based on a ZnO nanoflakes/poly (N-vinylcarbazole) hybrid. A transparent conducting polymer poly(3,4-ethylene-dioxythiophene):poly(styrenesulfonate)-coated quartz substrate is employed as the anode in replacement of the commonly ITO-coated glass in order to harvest shorter UV light. The devices show a lower dark current density, with a high responsivity (R) of 7.27 × 103 A/W and a specific detectivity (D*) of 6.20 × 1013 cm Hz1/2/W−1 at 2 V bias voltage in ambient environment (1.30 mW/cm2 at λ = 365 nm), resulting in the enhancements in R and D* by 49% and one order of magnitude, respectively. The study sheds light on developing high-performance, large scale-array, flexible UV detectors using the solution processable method.
