Poly(l,3,4-oxadia2ole-2,5-diyl-vinylene) and poly(l,3,4-oxadia2ole-2,5-diyl-ethynylene) were synthesi2ed by polycondensation of fumaramide or acetylene-dicarboxamide with hydra2ine sulfate in PPA to study the effect of the two repeating units on polymer electronic and thermal properties (55). [Pg.534]

The latest review of the status and prospects of polymer electronics (Samuel 2000), by a young physicist working in Durham University, England, goes at length into the possibilities on the horizon, including the use of copolymer chains with a series of blocks with distinct functions, and the possible use of dendrimer molecules... [Pg.335]

Conducting Polymers Electronically conducting polymers (such as polypyrrole, polythiophene, and polyaniline) have attracted considerable attention due to their ability to switch reversibly between the positively charged conductive state and a neutral, essentially insulating, form and to incorporate and expel anionic species (from and to the surrounding solution), upon oxidation or reduction ... [Pg.124]

On the other hand, Doblhofer218 has pointed out that since conducting polymer films are solvated and contain mobile ions, the potential drop occurs primarily at the metal/polymer interface. As with a redox polymer, electrons move across the film because of concentration gradients of oxidized and reduced sites, and redox processes involving solution species occur as bimolecular reactions with polymer redox sites at the polymer/solution interface. This model was found to be consistent with data for the reduction and oxidation of a variety of species at poly(7V-methylpyrrole). This polymer has a relatively low maximum conductivity (10-6 - 10 5 S cm"1) and was only partially oxidized in the mediation experiments, which may explain why it behaved more like a redox polymer than a typical conducting polymer. [Pg.587]

As the number of silicon atoms in the delocalized backbone cr-electron system increases, the number of HOMO and LUMO states increases, resulting in a band structure for high molecular weight polymers. Electronic absorptions from the HOMO (cr) to LUMO (essentially a ) are responsible for the characteristic UV absorption of polysilanes observed between 300 and 400 nm, the transition moment for which is in the direction of the Si chain.198 Polysilanes are... [Pg.587]

For a fast catalytic reaction, free access of gas, electrons, protons and water is needed. This leads to a best compromise of the volume fractions of protonconducting polymer, electron-conducting carbon, active sites and void space. [Pg.320]

The first devices of this type appeared in the early 1970s (Barbe and Westgate, 1970). The field of OFETs literally exploded in the mid-1980s when the first claims of flexible polymer electronics were made (Kozeuka et al., 1987). The subject was first reviewed by Horowitz (1998) and hundreds of OFET-related papers have been published since. [Pg.258]

The aim of this chapter is to present a simple but general band structure picture of the metal-semiconductor interface and compare that with the characteristics of the metal-conjugated polymer interface. The discussion is focused on the polymer light emitting diode (LED) for which the metal-polymer contacts play a central role in the performance of the device. The metal-polymer interface also applies to other polymer electronic devices that have been fabricated, e.g., the thin-film field-effect transistor3, but the role of the metal-polymer interface is much less cruical in this case and... [Pg.64]

Novel hybrid materials have been realized in which fullerenes participate in composite films with 7r-conjugated-polymer electron donors such as oligothio-phenes. Established studies have already shown that the photoinduced electron transfer is rather enhanced between 7r-conjugated polymers and fullerenes, while back electron transfer is considerably slower [145,149,171,172].Electrosynthe-sized polythiophene with pendant fullerene substituents was recently obtained from the corresponding biothiophene-fulleropyrrolidine dyad [173]. The novel material described has the potential of a double-cable polymer, heavily loaded with fullerene electron-conducting moieties. [Pg.15]

If we compare the data in Table 8.5 with the barrier requirements set in polymer electronics (Fig. 8.11), it is evident they cannot be met with metallized films, not even with ultra-high-barrier films, multi-layer structures from metal evaporation, and polymeric layers. For transparent barriers, as required for OLEDs, displays, organic solar cells, etc., evaporated oxide layers are even further from meeting the values required. [Pg.197]

For barriers in polymer electronics, evaporated layers cannot be used alone. Specific combinations of layers must be developed for that purpose. [Pg.197]

In 2000, 162000000 kg metallized web material (10-15 billion m2) were used for packaging applications in Europe of these 42% were OPP, 12% PET, and 40% metallized paper. The remaining 6% is accounted for by other metallized films, for example PE, PVC, PA, or cellophane, and metallized boards or tissues. An annual growth rate of 3-4% is forecasted [17, 18]. An approximately equally quantity of metallized film is used for decorative and technical applications. For these, however, PET is the dominant substrate. In technical applications, capacitor foil currently has a large share. RFID and EAS technology and polymer electronics are wide fields of potential applications and future growth for metallized substrates. [Pg.202]
