Conducting polymer poly

The conducting polymer poly(sulfur nitride) is unusual in that it is crystalline, consisting of chains of sulfur and nitrogen packed in parallel. 

The group in the Swiss Federal Institute of Technology [55] has fabricated a macroscale device by depositing the conducting polymer (poly(/j-phenylenevinylene)) on the MWCNT film (Fig. 16). They have observed the characteristic rectifying effect from the l-V curve, which suggests the CNTs inject holes efficiently into the polymer layer. However, due to the difficulty in...

Thus, from a solid-state chemistry point of view, the conducting polymer poly-3-methyl thiophene is in the reduced state, a semiconductor with a band structure. Intercalating with ions and oxidizing makes the compound behave as a metal from 0.45 to 1.1 Von theNHS.

At present a few studies of nanofibers and nanombes are focused on CNS drug delivery. One study evaluated electrospun nanofibers of a degradable polymer, PLGA, loaded with antiinflammatory agent, dexamethasone, for neural prosthetic applications (Abidian and Martin, 2005). A conducting polymer, poly(3,4-ethylenedioxythiophene), was deposited to the nano-fiber surface and the coated nanofibers were then mounted on the microfabricated neural microelectrodes, which were implanted into brain. The drug was released by electrical stimulation that induced a local dilation of the coat and increased permeability. 

Tables 6-9 give the device structures and performance metrics for monochromatic OLEDs that utilize organometallic emitters. Eigures 38-42 show the molecular structures for the various materials used in these devices. White OLEDs have also been prepared with these materials, but these will be discussed in a later section. Light-emitting electrochemical cells are treated in a separate section as well, since the finished devices have different operating characteristics than either of the other solution or vapor processed devices. Table 6 lists devices made solely with discrete molecular materials, while Table 7 gives data for devices made using polymeric materials. The only exception to the use of discrete molecular materials in Table 6 is for devices that use a conducting polymer, poly(3,4-ethylenedioxythiophene polystyrene sulfonate) (PEDOT), as a material to enhance the efficiency for hole injection into the organic layer. The mode of preparation for a given device is listed with the device parameters in the...

The first, rather extensive section focuses on polyacetylene. It presents a number of concepts which will not be reintroduced in later sections. The rationale is that the studies of polyaeetylene have been the most comprehensive of all and have preceded similar studies on other conducting polymers. The other two early conducting polymers, poly(para-phenylene) and polypyrrole, will be considered next. Subsequent sections deal with the new polymers, poly(para-phenylene... 

Another option is the replacement of carbon as electronic conducting carrier material and the proton-conducting Nafion in the electrode layer as well by a conducting polymer, by which an improvement of the interfacial properties was expected [83]. The manufacture of a Pt/Ru-polymer nanocomposite was successfully carried out and first samples were tested in a DMFC. As electronically conducting polymers, poly(N-vinyl-carbazole) and poly(9-(4-vinyl-phenyl)-carbazole were... 

NP of the conducting polymer poly(N-ethylaniline) and poly(N-methylaniline) can be prepared using a green approach, i.e., photocatalytic oxidative polymerisation. These polymeric nanomaterials exhibit enhanced antimicrobial activity against various pathogenic bacteria and therefore, find potential applications in biomedical sciences.
