“…The conductivity of the dopant (poly (o-toluidine)) is calculated at different temperature started from 1.70E-04 (S/cm) at 308K to 2.39E-04 (S/cm) at 387K [11] which is reacted with the PU by forming hydrogen bond between the POT segmented and TDI segmented .The I-V characteristic of the prepared samples with different thickness are shown in Fig. 5 which is displayed ohmic behavior [18,19].…”

The Toluene 2, 4-diisocyanate (TDI) (C9 H6 N₂ O₂) and polyethylene glycol (PEG) [H(OCH₂CH₂) OH] were used to prepare the poly urethane (PU), and then it is doped by different weight ratios of poly (o-toluidine) as (20%, 30%, and 50% w/w). The current-voltage (I-V) characterization of prepared thin films (deposited by spin coating method) showed ohmic behavior and the electrical conductivity increased with respect to increasing the ratio of dopant and all samples reflect a semiconductor material.

“…Poly(o-toluidine) is one of substituted derivative of polyaniline in which -CH 3 group is introduced at ortho position of benzenoid ring of polyaniline. MacDiarmid and co-workers suggested that substitution of methyl group at ortho position, increases steric interactions between benzenoid rings along the polymer chains, resulting decrease in the extent of conjugation 36 poly(o-toluidine) shows faster reversibility between oxidized and reduced form therefore chosen as an active conductive polymer along with polyaniline 37,38 .…”

Chemically oxidative polymerisation of N-methylaniline and o-toluidine with 5 molar ratios was performed using potassium persulfate as an oxidant in a H 2 SO 4 medium at 0-5 o C. The resulting copolymers were characterized by using UV-Visible and Fourier Transform IR spectroscopy. Two probe techniques were used to measure the electrical conductivity of the copolymer. The structural characteristics and particle size were determined through XRD experiments. The results showed that the conductivity of the copolymer (60% PNMA 40%POT) was found to be 5.932x10 -3 s/cm.

Lightweight and solution processible thin sheets of poly(o-toluidine)-carbon fiber-novolac composite for EMI shielding

An attempt has been made to generate lightweight and processible thin sheets of poly (o-toluidine)-carbon fiber (PoTCF) composite for electromagnetic interference shielding. PoTCF composite synthesized by oxidative emulsion polymerization was physically blended with different weight ratios of novolac resin to prepare a new class of composite material, which was further processed to form thin sheets (thickness of $0.85 mm) by a compression moulding technique. In situ incorporation of carbon fiber into the polymer matrix leads to the formation of composites with improved mechanical, thermal, electrical and shielding properties, which were further optimized by varying the amount of novolac resin in the sheets.Structural and morphological studies were carried out by UV-vis, FTIR, XRD and SEM. PoTCF composite sheets with 50 wt% loading of novolac resin have flexural strength of 36.0 MPa and exhibit a shielding effectiveness of 24 dB in the X-band (8.2-12.4 GHz) at a critical thickness of $2.11 mm, which is more than the limit required for techno-commercial applications. Therefore, indigenously fabricated polymerbased sheets would be potentially useful for making durable enclosures for electronic equipment.
