Razak, S. I. A., Rahman, W. A. W. A., Yahya, M. Y. (2013). Para-hydroxybenzene Sulfonic Acid as a Suitable Dopant for the Preparation of Conductive Epoxy/Polyaniline Nanowires Nanocomposites Blend: Electrical vs Mechanical Properties. Polymer-Plastics Technology and Engineering, 52, 1266-1270.
This article reports improved mechanical properties of epoxy/polyaniline nanowires nanocomposite (EP/PANI) by using para-hydroxybenzene sulfonic acid as the dopant. The PANI nanowires show no chain dedoping in the EP. Mechanical properties of the nanocomposites were maintained while achieving its conductive state and revealed pull-out of bundles rather than individual nanowire.

Conducting kenaf/polyaniline (KF/PANI) biofibers were successfully prepared via in situ oxidative polymerization. It was demonstrated, for the first time, the possibility of imparting new electronic properties on KF by coating with acid-doped PANI. The morphological analysis revealed three different PANI morphologies on the KF, depending on the type of acid doping. Enhanced interaction was achieved between the fiber-PANI surfaces, mainly from the π − π interactions. The newly developed conducting biofibers achieved enhancement in DC conductivity up to fivefold compared to the unmodified KF. Mechanical test on the conducting biofibers revealed no significant loss in the tensile properties.

Environmental awareness and depletion of the wood resources are among vital factors that motivate various researchers to explore the potential of agro-based crops as an alternative source of fiber material in paper industries such as writing, printing, wrapping, and packaging. Fibers from agro-based crops are available in abundance, low cost, and most importantly its biodegradability features, which sometimes referred as “ecofriendly” materials. This paper reports the effects of mercerization (NaOH treatment) on the properties of pineapple leaf fiber (PALF) pulp and paper. The individual fibers were characterized having good tensile properties at 15% NaOH treatment and favourable structural properties as characterized by Fourier transform infra-red (FTIR) spectroscopy and X-ray diffractometer (XRD). It was also shown that the PALF paper achieved desirable tear index value and uniform morphological observations at 15% NaOH concentration. This type of chemical treatment is useful to obtain PALF based paper products.

Razak, S. I. A., Sharif, N. F. A., Muhamad, I. I. (2014). Polyaniline Coated Halloysite Nanotubes: Effect of Para-Hydroxybenzene Sulfonic Acid Doping. Composite Interfaces, 21, 715-722.
This paper reports new method of preparing electrically conducting polyaniline-coated halloysite nanotube (HNT-PANI) by using para-hydroxybenzene sulfonic acid as the doping agent. The achieved DC electrical conductivity of the HNT-PANI was 9.83 × 10-2 Scm-1. The HNT revealed no damages by the acid doping while achieving its conductive state. The HNT-PANI exhibits polaronic transitions, existence of favorable IR peaks and Raman scattering, increased thermal stability, and desirable morphological characteristic as a result of the in situ coating. Such electronically modified tube-like clay could be useful in many applications such as conductive fillers in nanocomposites and drug delivery with the advantage of being cost effective. © 2014 © 2014 Taylor & Francis.

Razak, S. I. A., Rahman, W. A. W. A., Hashim, S., Yahya, M. Y. (2013). Polyaniline and their Conductive Polymer Blend: A Short Review. Malaysian Journal of Fundamental and Applied Sciences, 9, 74-80.
This short review discusses recent research regarding conductive polymeric blends containing polyaniline (PANI). Conducting PANI was reviewed in view of their properties to be used as a conducting component in several polymer matrix composites. Conductive PANI blends shows promise since the discovery of conducting polymers itself. These composite materials have introduced practical applications in various fields, including electromagnetic shielding and microwave absorption, static electricity dissipation, conducting membrane materials, conductive paint coatings and sensor materials. Highlights were made on PANI containing composites of polyethylene, polyamides, rubbers and elastomers, including other conventional thermoplastics and thermosets. Their electrical properties (percolation threshold and resistivity), blends preparation, drawbacks and potential usage were discussed in detail.
