“…Thin film polyaniline coatings are transparent, both to exciting radiation and to the intrinsic photoluminescence. One important feature of coordinated polymers is their ability to change their electrical and optical characteristics as the degree of oxidation varies [7]. The electrochromic effect characteristic of thin film polyaniline coatings may find application in organic displays, optical gating and filtering systems, and optical sensors [7][8][9][10].…”

Changes in the intensity of light transmitted through polyaniline films caused by an external voltage are used to control the photoluminescence spectrum of nanoporous silicon. A study of the optical-luminescence properties of hybrid porous silicon-polyaniline structures under the influence of an applied external potential shows that polyaniline films deposited on a porous silicon surface can serve as an optical filter for the photoluminescence of porous silicon with an electrically controlled transmission band.

“…These polymers present p-electron delocalisation, arising from conjugated double bonds in the polymer backbone. They are usually termed conducting polymers, since they can show very high electrical conductivity in doped states (p-doping or n-doping), although being insulators when undoped (neutral state) [3].…”

Estudo do efeito dos parâmetros de síntese na condutividade elétrica do compósito fluoreto de polivinilideno / polianilinaStudy of the effect of synthesis parameters in the electrical conductivity of the composite poly (vinylidene fluoride) / polyaniline ABSTRACTThe electroactive polymers have been the subject of many studies in the last decade, mainly because its unique properties. They are used in composite structures, which allow its application in many fields, as for example, sensors and artificial muscles. The electrical properties of these composites are influenced by the doping state of the electroactive polymer, which is controlled during its synthesis process. Therefore, this work aimed to evaluate how the synthesis parameters influence the electrical conductivity of the composite PANI/PVDF.The synthesis parameters evaluated were the concentrations of monomer, initiator and dopant, and the synthesis time. PANI was obtained by chemical polymerization in a solution containing PVDF and the solvent DMF. To evaluate possible changes in the chemical structure of the composite, the samples were submitted to FT-IR and XRD analysis. It was possible to conclude that the parameters relative to the production of PANI directly influence in the electrical conductivity of the composite. So, the sample produced with major quantities of monomer, initiator and dopant were statistically significant to increase the electrical property of the composite.

The cobalt phthalocyanine (CoPc) thin films (300 nm thick) deposited on n-type silicon substrate have been studied using micro-Raman spectroscopy, atomic force spectroscopy (AFM) and I-V measurement. The CoPc thin layers have been deposited at room temperature by the quasi-molecular beam evaporation technique. The micro-Raman spectra of CoPc thin films have been recorded in the spectral range of 1000 cm −1 to 1900 cm −1 using 488 nm excitation wavelength. Moreover, using surface Raman mapping it was possible to obtain information about polymorphic forms distribution (before and after annealing) of metallophthalocyanine (α and β form) from polarized Raman spectra. The I-V characteristics of the Au/CoPc/n-Si/Al Schottky barrier were also investigated. The obtained results showed that influence of the annealing process plays a crucial role in the ordering and electrical conductivity of the molecular structure of CoPc thin films deposited on n-type silicon substrate.
