Polymers, inorganic conducting

In addition to thermal polymerization, it is possible to polymerize CPD with inorganic haUdes as catalyst. With trichloroacetic acid as the catalyst, deeply colored, blue polymers that conduct electricity in nonpolar solvents such as benzene in the presence of acid can be obtained. The conductivity and color are caused by blocks of conjugated double bonds present in the polymers (20—21).

As the conductive polymers are similar to various other materials such as amorphous polymers, inorganic intercalates, semiconductors, solid electrolytes and metals in one way or the other and these materials show wide range of degradation kinetics in different environments as well as dependence on temperature and the composition of the material. Hence, the predictions about degradation behaviour seem to be risky without experimental data. Also, one has to be very careful in extrapolating the available data which may lead to erroneous results.

Due to the enhanced conductivity and consequent improved electrochemical performance, the cathode materials of conjugated polymers/ inorganic have attracted much attention in a wide range, and some novel nanostructures have been recently proposed. Mai et al. reported the preparation of coaxial or triaxial nanowires of MoO and AgVO coated with conducting PTh or PANI based on the in situ polymerization method [29,76], and the capacity retention rates were significantly enhanced due... 

As a powerful methodology to assemble various components into soft supramolecular organizations, the LbL assembly method shows continuous progresses in the fields of drug delivery under the supramolecular concept (Fig. 2.2.5). The LbL method has excellent versatility for the assembly of various kinds of substances [13]. This method covers a wide range of available materials including proteins, nucleic acids, saccharides, virus particles micelles, vesicles, LB films, and other lipid membranes as well as conventional polyelectrolytes, conductive polymers, inorganic nanomaterials, nanocarbons, and dye... 

Fillers coated by conducting polymers Inorganic-organic particles and fibers can be coated with conducting polymers such polypyrrole (Ouyang and Chance 1998). 

It is possible to prepare composites of nonconducting polymer/inorganic salt by dispersing inorganic salts in the organic matrix via complexation. The electrical conductivity of such materials has been well established in view of their importance as solid polymer electrolytes in solid state batteries (14J5). 

The structure and properties of such polymer-inorganic hybrid materials substantially depend on the method of reduction of the metal ions [81, 114, 115, 132,133], The chemical reduction of Cu in IPEC matrices leads to the formation of copper protoxide NPs [81]. Micrographs of the irradiated film demonstrate that their size is of about 10 nm. The electric conductivity of the prepared hybrids is very low (Table 3). 

Nanoporous materials have been produced by the polymerization of bicontinuous microemulsions containing polymerizable surfactants in addition to water and monomer [107]. Polymerizable surfactants, also called surfmers, are amphiphilic substances containing a polymerizable double bond [108]. A similar technology has been used to synthesize ion-conductive membranes [109], luminescence films [110], and polymer-inorganic nanocomposites [111].
