Miniaturization, nanocomposites, nanotubes, nanopolymers used as vectors for active ingredients, micro-processors and photovoltaic cells based on electrically conducting polymers plastics are each time veetors of news. Sinee their origin, they have constantly revolutionized the way we live, whether it is in terms of comfort, safety, health, communication, transportation, architecture, design, sports or leisure. 

Polymer-based nanocomposites reinforced with nanoparticles (NPs) have attracted much interest due to their homogeneity, relatively easy processability, and tunable physicochemical properties, such as mechanical, magnetic, electric, thermoelectric, and electronic properties [2,19-36], High particle loading is required for certain industrial applications, such as electromagnetic-wave absorbers [37,38], photovoltaic cells (solar cells) [39,40], photo detectors, and smart structures [41 3]. A nanoparticle core with a polymer shell renders many industrial applications possible, such as nanofluids and magnetic resonance imaging (MRI). 

The combination of favorable properties of PANI and TiO opens the possibility for various applications of PANI/TiO nanocomposite materials, such as piezoresistivity devices [41], electrochromic devices [99,118], photoelectrochemical devices [43,76], photovoltaic devices/solar cells [44,50,60,61,93,119], optoelectronic devices/UV detectors [115], catalysts [80], photocatalysts [52,63,74,75,78,84,87,97,104,107,121,122,125], photoelectrocatalysts [122,123], sensors [56,61,65,69,85,86,95,120,124], photoelectrochemical [110] and microbial fuel cells [71], supercapacitors [90,92,100,109,111], anode materials for lithium-ion batteries [101,102], materials for corrosion protection [82,113], microwave absorption materials [77,87,89], and electrorheological fluids [105,106]. In comparison with PANI, the covalently bonded PANI/TiO hybrids showed significant enhancement in optical contrast and coloration efficiency [99]. It was observed that the TiO nanodomains covalently bonded to PANI can act as electron acceptors, reducing the oxidation potential and band gap of PANI, thus improving the long-term electrochromic stability [99].

The exciton photodissociation, charge transport, and the photovoltaic response of PVK/Ti02 nanocomposites for solar-cell applications have been assessed [210]. 

The current-voltage characteristics under white illumination exhibit a dramatic increase in short-circuit current density and open-circuit voltage for a 30% I1O2 content. There the best dispersion of the Ti02 particles takes place. It has been concluded that the photovoltaic properties of these nanocomposites are controlled by the interfacial area between the donor and the acceptor material and further are Umited by the dispersion of the nanoparticles in the polymer [210].

Nanocomposites are multiphased materials with at least one phase in the nanometer range. The mechanical, electrical, thermal, optical and electrochemical properties of nanocomposites are different from that of component materials. Nanocomposites have potential applications in almost every field of the modern day scenario. They play a key role in tailoring properties to suit any technology and have potential applications like light-emitting diodes, photodiodes, photovoltaic cells, smart microelectronic devices, gas sensors, etc.
