Such hybrid molecules and supramolecular solids offer the promise of systems with the flexibility, strength, toughness, and ease of fabrication of polymers, with the high temperature oxidative stability of ceramics, and the electrical or catalytic properties of metals. Polyphosphazene chemistry provides an illustration of what is possible in one representative hybrid system.

Today, polymeric materials are used in nearly all areas of daily life that it is right to claim that we live in a polymer age. The evidence is all around us. Polymers are used in shelter, clothing, health, food, transportation, and almost every facet of our lives. In fact, it is hard to imagine what the world would be like without S3mthetic polymers. Production and fabrication of polymers are major worldwide industries. The data presented in Tables 14.1 to 14.8 indicate the size of the polymers marketplace in the 1992 to 2002 decade [1]. 

Progress has been made in the search for new lanthanide /3-diketonates as sources of luminescence, with application in the fabrication of polymer light-emitting diodes for low-cost, full-color, flat-panel displays.16,17 Moreover, some complexes seem promising as chiral NMR reagents for the determination of enantiomeric purity18,19 and prospective catalysts in many organic syntheses.20... 

ZITO films with composition ZnIn2,oSni,502 have been prepared by CVD experiments employing [In(dpm)3], [Sn(acac)2], and [Zn(hfa)2(diamine)], (hfa = hexafluoroacetylacetonato). Such films were used in the fabrication of polymer light-emitting diodes, which exhibited light outputs and current efficiencies almost 70% greater than those of commercial Sn-doped indium oxide (ITO) films. ...

Recently the idea of Ago et al. to replace the ITO electrode by a CNT based electrode was pursued by several groups again. However, this time SWNTs were used [330-333]. The motivation for this step is generally found in the benefit of replacing an expensive vacuum step in the fabrication of polymer solar cells [330] with roll-to-roll production of supporting nanotube electrodes (Fig. 67) [331], which will aid in the removal of ITO and PEDOT PSS related problems [332] while facilitating applications of flexible devices on plastic substrates [333].

Fabrication of polymer inhibited films (PIF) and hardware packaging must be accomplished by observance of these generally accepted requirements and hygienic norms together with the following specific demands. 

PCSL microfabrication is an attractive alternative for making robustly enclosed microchannels by solvent bonding, while protecting microchannel integrity using a sacrificial material. This technique does not require sophisticated thin-film deposition instrumentation and should be easy to implement by microfluidics researchers. In the next section, we provide guidelines for the fabrication of polymer microfiuidic systems using PCSLs.

We will see later that the desirable mechanical properties, such as resistance to cracking, improve as Mn increases. On the other hand, the ease of fabrication of polymers by melt processing decreases rapidly as M increases. Commercial polymers therefore have MWDs that are the best compromise for a particular process and application area. There is a trend to manufacture polymers of narrower MWD, to improve mechanical properties without sacrificing processability. 

Poly[2-methoxy-5-(2 -ethyl-hexyloxy)-l,4-phenylene vinylene] (MEH-PPV) is an excellent conjugated polymer and broadly used in polymer photoelectron devices, but is difficult to electronspin directly. In the work by Zhao et al, core-shell structured nanofibers were fabricated by coaxial electrospinning MEH-PPV (shell) in chlorobenzene and PVP (core) in 1,2-dichloroethane [64]. MEH-PPV was soluble in the above two solvents, which prevented the precipitation of MEH-PPV and enhanced the adhering action between the two polymers in the coaxial electrospinning process. It should be noted that this is an unusual example of core-shell nanofibers where (a nonprocessable) PPV was spun as the shell and not in the core. These uniform core/shell PVP/MEH-PPV nanofibers with a highly fluorescent property can have potential applications in the fabrication of polymer nanophotoelectron devices.
