Design and development of cellulosic bionanocomposites from forestry waste residues for 3D printing applications

Author: Mathew, Maya J ; Dyanti, Nokuzola ; Mokhena, Teboho C ; Agbakoba, Victor ; Sithole, Bishop B Date: Jun 2021 This paper deals with the development of cellulose nanofibres (CNFs) reinforced biopolymers for use in packaging applications. Cellulose nanofibres were extracted from sawdust by a combination of chemical and mechanical treatments. The extracted ... Read more
Effect of alkaline pretreatment on the thermal behavior and chemical properties of rice husk varieties in relation to activated carbon production

Author: Menya, E ; Olupot, PW ; Storz, H ; Lubwama, M ; Kiros, Y ; Mathew, Maya J Date: 2020 Thermal behavior and chemical properties of selected raw and NaOH-pretreated rice husk varieties were investigated. NaOH-pretreatment process involved soaking 5 g rice husk samples in 40 mL of 2%w/v NaOH, shaking (400 rpm) and heating (50 °C) ... Read more
Effect of clay nanofillers on the mechanical and water vapor permeability properties of xylan–alginate films

Author: Naidu, Darrel S ; Mathew, Maya J Date: Oct 2020 In this study, xylan–alginate-based films were reinforced with nanoclays (bentonite or halloysite) by the solvent casting technique. The effect of the nanoclay loadings (1–5 wt %) on various properties—mechanical, optical, thermal, solubility, ... Read more
Effect of expandable graphite on thermal and flammability properties of poly(lactic acid)-starch/poly(E-caprolactone) blend systems

Author: Mngomezulu, ME ; Luyt, AS ; Chapple, Stephen A ; Mathew, Maya J Date: Sep 2018 The effect of expandable graphite (EG) on the flammability and thermal stability of a poly(lactic acid) (PLA)-starch/poly(E-caprolactone) (PCL) blend was investigated. The samples were prepared by melt-mixing and characterized by thermogravimetric ... Read more
Electrospun alginate nanofibers toward various applications: A review

Author: Mokhena, Teboho C ; Mochane, MJ ; Mtibe, Asanda ; Mathew, Maya J ; Sadiku, ER ; Sefadi, JS Date: Feb 2020 Alginate has been a material of choice for a spectrum of applications, ranging from metal adsorption to wound dressing. Electrospinning has added a new dimension to polymeric materials, including alginate, which can be processed to their ... Read more
Engineered transparent wood composites: A review

Author: Jele, Thabisile B ; Andrew, Jerome E ; Mathew, Maya J ; Sithole, Bruce Date: May 2023 Wood is a versatile resource due to its inherent properties such as low density, good weight to strength ratio, unique hierarchical structure, microscale pores, and ease of processing, including its biodegradability and renewability. In the ... Read more
Esterified cellulose nanofibres from saw dust using vegetable oil

Author: Mokoena, Teboho P ; Mathew, Maya J Date: Apr 2020 In this work, cellulose nanofibres (CNFs) were extracted from sawdust, which is an underutilized by-product from the wood and timber industry. The extracted CNFs by chemical and mechanical treatments had a web-like structure with diameters ... Read more
Mechanical and shape memory properties of 3D-Printed Cellulose Nanocrystal (CNC)-reinforced polylactic acid bionanocomposites for Potential 4D applications

Author: Agbakoba, Victor C ; Hlangothi, P ; Andrew, Jerome E ; Mathew, Maya J Date: Sep 2022 There is a growing need for diversified material feedstock for 3D printing technologies such as fused deposition modelling (FDM) techniques. This has resulted in an increased drive in the research and development of eco-friendly biopolymer-based ... Read more
Morphology, thermal and dynamic mechanical properties of poly(lactic acid)/expandable graphite (PLA/EG) flame retardant composites

Author: Mngomezulu, ME ; Luyt, AS ; Mathew, Maya J Date: Dec 2017 This work reports on the effect of expandable graphite (EG) on the morphology, thermal and dynamic mechanical properties of flame retardant poly(lactic acid) (PLA)/EG composites. The composites were prepared by melt-mixing and their structure, ... Read more
Structure and properties of lignin-based biopolymers in polymer production

Author: Motsoeneng, TS ; Mochane, MJ ; Mokhena, Teboho C ; Mathew, Maya J Date: 2020 Lignin 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
Transitioning from conventional plastic to more sustainable alternative materials: Evidence from South Africa

Author: Oelofse, Suzanna HH ; Nahman, Anton ; Russo, Valentina ; Stafford, William HL ; Muswema, Aubrey P ; Mathew, Maya J ; Muniyasamy, Sudhakar Date: Oct 2022 The Council for Scientific and Industrial Research in partnership with UNIDO and the University of the Witwatersrand, with funding from the Japanese government, undertook research to identify and implement opportunities for sustainable ...
