摘要： A method for producing flexible, nanoparticle-polymer composite electrodes is described. Conductive nanoparticles, preferably metal nanowires or nanotubes, are deposited on a smooth surface of a platform to produce a porous conductive layer. A second application of conductive nanoparticles or a mixture of nanoparticles can also be deposited to form a porous conductive layer. The conductive layer is then coated with at least one coating of monomers that is polymerized to form a conductive layer-polymer composite film. Optionally, a protective coating can be applied to the top of the composite film. In one embodiment, the monomer coating includes light transducing particles to reduce the total internal reflection of light through the composite film or pigments that absorb light at one wavelength and re-emit light at a longer wavelength. The resulting composite film has an active side that is smooth with surface height variations of 100 nm or less.

摘要： The synthesis, characterization, optical and electrochemical properties of a regioregular copolymer, poly(3-octylthiophene-2,5-diyl-co-3-decyloxythiophene-2,5- diyl) (POT-co-DOT), and an alternating regioregular copolymer poly{(9,9- dioctylfluorene)-2,7-diyl-a/f-[4,7-bis(3-decyloxythien-2-yl)-2, 1,3-benzothiadiazole]- 5',5"-diyl} (PF-co-DTB) is disclosed. The incorporation of 3-alkoxythiophene units onto the conjugated backbones enhances the electron-donating property of the polymer and lowers its bandgap. The fabrication and performance of photovoltaic cells with bulk heterojunction architecture based on blends of these copolymers with PCBM are also described.

摘要： 41 Polymerizable anions and/or cations can be used as the ionically conductive species for the formation of a p-i-n junction in conjugated polymer thin films (FIG. 5C). After the junction is formed, the ions are polymerized in situ, and the junction is locked thereafter. The resulting polymer p-i-n junction diodes could have a high current rectification ratio. Electroluminescence with high quantum efficiency and low operating voltage may be produced from this locked junction. The diodes may also be used for photovoltaic energy conversion. In a photovoltaic cell, the built-in potential helps separate electron-hole pairs and increases the open-circuit voltage.

摘要： A refreshable tactile display using a bistable electroactive polymer with a stretchable serpentine Joule heating electrode. A portable refreshable tactile display with Braille standard resolution has been demonstrated. The steep modulus change of BSEP over a narrow temperature range achieves a device with high blocking force of over 50g and large displacement of 0.7mm. A "P3R" fabrication process of Prestretch-Pattern-Protect-Release is effective to form a S-CNT electrode in the wrinkled surface layer with high compliancy and resistance-consistence up to 188% area strain. The electrode can soften the BSEP film at 30 V in less than 1 s. The simple architecture of the tactile display ensures an easy and low-cost fabrication. The demonstrated refreshable tactile display should find a wide range of applications in recreation, entertainment, robotics, health care, and so on.

摘要： A composition of matter useful as a bioadhesive including a bistable adhesive polymer. The bistable adhesive polymer includes one or more polymer backbones; side-chains attached to each of the polymer backbones; and one or more transition temperatures between a crystalline state and an amorphous state. The one or more transition temperatures are such that the polymer transitions from the crystalline state to the amorphous state upon physical contact with biological tissue having a temperature higher than the transition temperature. The polymer adheres or attaches to the biological tissue in the amorphous state and can be peeled from the biological tissue when cooled below the transition temperature to the crystalline state.

摘要： A solid-state heat transporting device including a heat transporting element whose uniformity of contact with one or multiple surfaces is controllable so that various amounts of heat may be transported to and from the one or multiple surfaces. The heat transporting element uses the electrocaloric effect to absorb and release the heat and the uniformity of contact is controlled using an electrostatic effect which may change the shape of the heat transporting element. In one embodiment, the heat transporting element is an electrostatically actuated P(VDF-TrFE-CFE) polymer stack achieving a high specific cooling power of 2.8 W/g and a COP of 13 (the highest reported coefficient of performance to date) when used as a cooling device.

摘要： A method for the synthesis and use of transparent bulk conjugated polymers prepared from liquid monomers via bulk polymerization. The liquid monomer contains pi-electron conjugated moieties and polymerizable moieties. The monomer solution may also have functionalizing additives such as a luminescence additive that includes organic dyes, luminescent molecules, fluorescent compounds, phosphorescent compounds, and luminescent quantum dots. The monomer solution may also have sensitizing additives such as high-energy photo sensitizing compounds, nanoparticles of compounds containing atoms with atomic numbers greater than 52 and neutron sensitizing additives. The monomer solution is polymerized by heating to an elevated temperature with or without addition of an initiator. Alternatively, the monomer is polymerized by photo-induced polymerization. A photoinitiator may be employed to initiate the photopolymerization. Scintillation materials with significant light yields are illustrated.
