Para-toluenesulphonic acid doped Poly(2-methylaniline) (PmANI) was synthesized by chemical method using ammoniumpersulphate (APS) as an oxidant. It was synthesized along with optimization studies w.r.t. varied dopant-monomer ratios for better DC conductivity. Various spectroscopies like XRD, UV-Vis and FT-IR were used to characterize the polymer. The behavior of DC conductivity with variation in temperature was studied with in the temperature range of 300 - 425 K and it was observed that conductivity rised to ~four orders with the surge in temperature. The experimental conductivity data was fitted with various conduction models to find the proper charge transport mechanism in this polymer.

Fashion is a phenomenon with a complex structure that changes according to time and place. Innovations in the form of clothing played an important role in the development of fashion. The idea of having a different style of clothing and being liked more paved the way for the emergence of fashion trends. Therefore, the importance of trademark image in the fashion sector has increased gradually. While consumers prefer the fashion trademark, they are more influenced by the trademark image. For this reason, trademark has become very important for businesses in the fashion sector. However, in order to become a trademark owner in the fashion sector, enterprises and undertakings should not have absolute refusal grounds at the time of trademark application. The absolute refusal grounds are related to public order and are therefore protected by international and national regulations. The absolute refusal grounds in our country have been prepared in Article 5 of Industrial Property Law No. 6769 in line with the European Union Directives and the agreements signed within the European Union. In this study, the absolute refusal grounds are discussed within the scope of Article 5 of Industrial Property Law No. 6769. In this direction, an evaluation was made in line with the recommendations of the European Court of Justice and the decisions of the Court of Cassation. In addition, the absolute refusal grounds were examined and examples from fashion and textile sectors were given.

“…Along these the different oxidation states PAni also exist as the emeraldine salt (ES) and its the only state that is electrical conductivity. Its the nature of the doping which effects the electrical conductivity of PAni salt [4]. A variety of different acids are used to protonate PAni and augment its conductivity [5,6].…”

Conductive Polyaniline PAni was synthesized chemical oxidative polymerization the chemical route. PAni thus synthesized was in-situ doped with HCl acid and Lithium perchlorate in different weight percentage. PAni and its different doped variant thin films were deposited on plain soda glass and conducting ITO glass using CBD technique. Samples of different configurations are characterized for structural consistency with X-ray, for chemical identification with FTIR, for thermal integration with DSC. Electric measurements such as capacitance and conductance were carried out using LCR bridge and Four Probe arrangements respectively. X-ray analysis divulges largely the polycrystalline nature of PAni and LiClO 4 doped variant. IR study in Fourier transformed mode reveals PAni and its doped variants maintains their structural integrity in good agreement with standard pronounced peaks in the region of 2000-3500 cm-1 , though displaced hydrogen bonds in doped PAni leads to a slight shifting. Significant thermal stability for doped and undoped Polyaniline nearly up to 200 0 C is noted with DSC. Dielectric measurements with variable temperature in the frequency range 50 Hz-2 MHz yields the capacitance variation, confirming the interfacial polarization within the PAni matrix. Lithium Conductivity of 6.19 Sm-1 for lithium perchlorate doped PAni again affirms exitance of bipolarons at greater level of oxidation.
