“…Since TiO 2 is photoactive, the nanocomposite is used to build hybrid (TiO 2 /PANI NF) solar cells. Rajappa et al, uses MCP to produce a NC including Fe 2 O 3 nanoparticles (FeOxNP) and a photoactive dye (tetraaminophthalocyanine (Zn),TAPcZn) [ 134 ]. The PANI covered the FeOxNPs and holds the photoactive dye.…”

The mechanochemical synthesis of polyanilines (PANIs), made by oxidative polymerization of anilines, is reviewed. First, previous knowledge of the polymerization reaction in solution is discussed to understand the effect of different parameters: oxidant/monomer ratio, added acid, oxidant, temperature and water content on the properties of the conducting polymers (molecular weight, degradation, doping/oxidation level, conductivity, and nanostructure). The work on mechanochemical polymerization (MCP) of anilines is analyzed in view of previous data in solution, and published data are critically reconsidered to clarify the interpretation of experimental results. A key factor is the production of acids during polymerization, which is often overlooked. The production of gaseous HCl during MCP of aniline hydrochloride is experimentally observed. Since some experiments involves the addition of small amounts of water, the kinetics and heat balance of the reaction with concentrated solutions were simulated. A simple experiment shows fast (<2 min) heating of the reaction mixture to the boiling point of water and temperature increments are observed during MCP in a mortar. The form and sizes of PANI nanostructures made by MCP or solution are compared. The extensive work on the production of nanocomposites by MCP of anilines together with different nanomaterials (porous clays, graphene, carbon nanotubes, metal, and oxide nanoparticles) is also described.

“…39-1882). 51,52 The XRD pattern of the Zn(II)TEPZCAPc@MWCNT hybrid exhibited all the reflections of Zn(II)TEPZCAPc with a lower intensity and a slight shift in the 2y angle. The decrease in the intensity and the slight shift in 2y angle may be due to the interaction of Zn(II)TEPZCAPc with the MWCNTs.…”
