In the meantime, this phenomenon has also been observed by other groups for thermosensitive polymer-based metal nanoparticles [77, 78]. Pich et al. have used microgel particles based on the copolymer of A-vinylcaprolactam (VCL) and ace-toacetoxyethyl methacrylate (AAEM) (PVCL/PAAEM) as the carrier system for the deposition of metal nanoparticles. The microgels were first modified with poly(3,4-ethylenedioxythiophene) (PEDOT) nanorods through an in situ oxidative polymerization process. Microgels with PEDOT nanorods in the shell were then used for the... 

Figure. 10 shows the atom force microscope (AFM) of a PEDOT composite with a percentage of 20 wt. % Ti02 nanoparticles (about 5 nm in size). With such a high resolution of the AFM one can see a distribution of nanoparticles in the polymer due to the spincoating process. For the pure polymeric PEDOT, the surface exhibits smoothness comparable to the one of the area surrounding the nanopjarticles. The Ti02 nanoparticles... 

The effect of nanoparticles in composite films used for both the emitting layer (EL) and HTL in OLEDs was revealed by measuring the I-V characteristics of the devices made from different layers, such as a single pure EL diode (ITO/MEH-PPV/ Al, abbreviated as SMED), a double pure polymer diode (ITO/PEDOT/MEH-PPV/Al or PPMD), a double polymeric... 

In the section devoted to CNTs, some details concerning synthesis and purification methods, as well as separation techniques for metalfic and semiconducting nanotubes will be reviewed. Some aspects concerning the interactions of CNTs with reactants used in the synthesis of different composites based on conducting polymers, such as PANI, PPy, PEDOT, PBTh, PNVK, PPV, and polyfluorene (PF) will be discussed in the section devoted to the synthesis of the CP/CNT composites. Preparing a composite with the desired properties requires knowledge of the interaction between the host matrix and the guest carbon nanoparticles. 

Covalentiy functionalization of SWNTs with CPs is a rehable method to produce soluble materials containing such nanoparticles. The following three composites (i) PANFCNTs (ii) PEDOT/CNTs and (iii) PVK/CNTs, are discussed in this section. In the first two cases the covalent functionalization involves covalent bonding of macromolecular chains both...

Cai et at developed PEDOT/PbTe composite by adding PbTe nanoparticles into a polymerization media [20]. The PEDOT nanotubes were in-situ fabricated by an interfacial polymerization method. The PbTe nanoparticles (-20-50 nm) acted as solid stabilizer and were adsorbed on the surface of the PEDOT nanotubes at the acetonitrile/n-hexane interface (Figure 6.10). The materials exhibit extremely large Seebeck coefficient values, which is promising for TE applications.
