The present invention relates to a one-step process for preparation of “in-situ” or “ex-situ” self-organized and electrically conducting polymer nanocomposites using thermally initiated polymerization of a halogenated 3,4-ethylenedioxythiophene monomer or its derivatives. This approach does not require additional polymerization initiators or catalysts, produce gaseous products that are naturally removed without affecting the polymer matrix, and do not leave by-product contaminants. It is demonstrated that self-polymerization of halogenated 3,4-ethylenedioxythiophene monomer is not affected by the presence of a solid-state phase in the form of nanoparticles and results in formation of 3,4-polyethylenedioxythiophene (PEDOT) nanocomposites.

The present invention provides a high-performance lithium-containing organic sulfur electrode material and a preparation method of an integrated flexible electrode. According to the present invention, 1,3-diisopropenyl benzene with diene bonds and Li2S6 are used as precursors to react to generate the lithium-containing organic sulfide Poly (Li2S6-r-DIB) through an in-situ polymerization method. The synthesized lithium-containing organic sulfide Poly (Li2S6-r-DIB) can be directly attached to a flexible conductive carbon cloth to prepare the integrated flexible electrode due to its good viscosity when heated to a certain temperature. The obtained flexible electrode has the advantages of high capacity, high flexibility, stable structure and the like.

An OLED panel includes a light emitting substrate and a color filter substrate. The light-emitting substrate includes a multi-layer OLED film emitting white light. The color filter substrate includes a color filter array, a conductive layer that is electrically connected to a wall-shaped elastic conductor that is wearing a metal cap. The two substrates are laminated together in a manner that the metal cap is in direct contact with cathode electrode of the OLED at the site of pixel definition layer. The total resistance of the cathode layer of the OLED is therefore reduced significantly, and voltage-drop on cathode and associated image artifacts are minimized.
