Correlation between the morphology and photo-physical properties of P3HT: fullerene blends

Author: Motaung, DE ; Malgas, GF ; Arendse, CJ Date: 2010 The photo-induced charge transfer and optoelectronic efficiency of the solar cells correlated to the morphology and the structure of P3HT:C60 blend was studied by means of photoluminescence and electron spin resonance (ESR). The occurrence ... Read more
Effect of water absorption on mechanical properties of flax fibre reinforced composites

Author: Guduri, BBR ; Khoathane, C ; Anandjiwala, RD ; De Veries, A ; Sadiku, ER ; Van Wyk, Llewellyn V Date: Jan 2007 Scutched and line flax fibres, with mean linear density of about 19.5 decitex, were utilized for this study. Mechanical properties of fibre and resin were measured for assessing their contribution in the composite matrix. Polypropylene (PP)/ ... Read more
Filament poisoning at typical carbon nanotube deposition conditions by hot-filament CVD

Author: Oliphant, CJ ; Arendse, CJ ; Malgas, GF ; Motaung, DE ; Muller, TFG ; Halindintwali, S ; Julies, BA ; Knoesen, D Date: May 2009 This paper reports on the poisoning of tungsten filaments during the hot-filament chemical vapour deposition process at typical carbon nanotube (CNT) deposition conditions and filament temperatures ranging from 1400 to 2000 °C. The morphological ... Read more
Physicochemical and morphological properties of poly(aniline-co-pyrrole)

Author: Mavundla, SE ; Malgas, GF ; Motaung, DE ; Iwuoha, EI Date: 2010 Copolymers of aniline and pyrrole have been prepared by chemical oxidative- olymerization of aniline and pyrrole using ammonium per sulphate and ferric chloride as oxidants. The structural and morphological properties were studied by X-ray ... Read more
Use of calcination in exposing the entrapped Fe particles from multi-walled carbon nanotubes grown by chemical vapour deposition

Author: Kesavan Pillai, Sreejarani ; Matlhoko, L ; Arendse, C ; Ray, SS ; Moodley, M Date: Mar 2009 Multi-walled carbon nanotubes (MWCNTs) were synthesized by a chemical vapour deposition method. The effect of calcination at temperatures ranging from 300 to 550°C in exposing the metal nanoparticles within the nanotube bundles was studied. ... Read more
