Author:Folorunso, O; Hamam, Y; Sadiku, R; Ray, Suprakash S; Joseph, ADate:Jul 2019The problem associated with mixtures of llers and polymers is that they result in mechanical degradation of the material (polymer) as the ller content increases. This problem will increase the weight of the material and manufacturing cost. ...Read more
Author:Mavundla, SE; Malgas, GF; Motaung, DE; Iwuoha, EIDate:2010Copolymers 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
Author:Ojijo, Vincent O; Ray, Suprakas SDate:2012In the recent years, biodegradable aliphatic polyesters-based composite materials have attracted substantial interest, primarily due to their sustainable production, use and end-life. This chapter discusses the preparation, characterisation, ...Read more
Author:Labuschagne, Philip W; Moolman, S; Maity, ArjunDate:Feb 2012Plastics are used increasingly in packaging applications due to a number of favorable properties, such as versatility, low weight, and low cost. However, their biggest drawback when compared to traditional packaging materials, such as glass ...Read more
Author:Ojijo, Vincent O; Ray, Suprakas SDate:Oct 2013In recent years, the development of environmentally friendly polymeric materials, which are primarily based on biodegradable polymers (from both fossil-fuel and natural resources) with balanced properties, has become the focus of considerable ...Read more
Author:Yalisi, B; Roro, Kittessa T; Forbes, ADate:May 2011Pulsed laser deposition (PLD) is a thin-film deposition technique, which uses short and intensive laser pulses to evaporate target material. The technique has been used in this work to produce selective solar absorber (SSA) thin film composites ...Read more

Author:Motaung, DE; Malgas, GF; Arendse, CJ; Mavundla, SE; Knoesen, DDate:Jul 2009Regioregular poly(3-hexylthiophenes) (P3HTs) and its blends were studied regarding their structural and photo-physical properties using fullerene as an electron acceptor material. Photo-physical and structural characteristics of the polymer ...Read more
Author:Motsoeneng, TS; Mochane, MJ; Mokhena, Teboho C; Mathew, Maya JDate:2020Lignin can be extracted from a variety of plants such as soft and hard wood which account for the different functional groups and contents as well as number average molecular weights. Different chemical treatments have been employed to isolate ...Read more
Author:Labuschagne, Philip WDate:Oct 2010The use of supercritical CO2 as medium in polymer processing eliminates many of disadvantages associated with other means of processing, i.e. high temperatures or toxic solvents. The “soft” processing conditions make CO2 specifically suitable ...Read more
Author:Aderibigbe, BA; Neuse, EW; Sadiku, ER; Shina Ray, S; Smith, PJDate:2014In this research, aminoquinoline compounds were synthesized, characterized and incorporated into water soluble polymers to form conjugates. The conjugates were characterized by X ray Diffraction (XRD), Thermal Gravimetric Analysis (TGA), ...Read more
Author:Botha, Natasha; Coetzer, R; Inglis, H; Labuschagne, JDate:Nov 2020Polymers are used in various industrial applications due to their ease of production, light weight and ductility. Adding fillers, such as clays, improves a range of thermo-mechanical properties, however manufacturing parameters may have an ...Read more
