Development of multifunctional nano/ultrafiltration membrane based on a chitosan thin film on alginate electrospun nanofibers.
Mokhena, Teboho Clement; Luyt, Adriaan Stephanus ( Elsevier , 2017 , Article)The aim of this study was to develop a high flux three-tier composite membrane composed of a coating layer based on chitosan and chitosan with silver nanoparticles, electrospun alginate nanofibres as a midlayer and ... -
Effect of blend ratio and nanofiller localization on the thermal degradation of graphite nanoplatelets-modified PLA/PCL
Luyt, Adriaan Stephanus; Kelnar, Ivan ( Springer Netherlands , 2019 , Article)A variety of poly(lactic acid) (PLA)-poly(ε-caprolactone) (PCL) samples with different PLA:PCL ratios, containing different contents of graphite nanoplatelets (GrP), were analysed in a thermogravimetric analyser (TG) under, ... -
Effect of surfactant and electron treatment on the electrical and thermal conductivity as well as thermal and mechanical properties of ehylene vinyl acetate/expanded graphite composites
Sefadi, Jeremia Shale; Luyt, Adriaan Stephanus; Pionteck, Jürgen; Piana, Francesco; Gohs, Uwe ( Wiley Periodicals, Inc , 2015 , Article)This study presents an investigation of the electrical and thermal conductivities of composites based on an ethylene vinyl acetate (EVA) copolymer matrix and nanostructured expanded graphite (EG). To improve the EG dispersion ... -
Impact of corona and radio-frequency plasma treatment on the degradation of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV)
Antunes, Ana; Popelka, Anton; Luyt, Adriaan Stephanus; Mahmoud, Abdelrahman; Aljarod , Omar Yosef; Hassan, Mohamed; Kasak, Peter... more authors ... less authors ( BME-PT and GTE , 2022 , Article)Poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) is a polyester, produced naturally by microorganisms, with excellent biocompatibility. Corona and radio-frequency (RF) plasma treatment were applied in order to improve ... -
Poly(lactic acid)-starch/Expandable Graphite (PLA-starch/EG) Flame Retardant Composites
Mngomezulu, Mfiso Emmanuel; Luyt, Adriaan Stephanus; Chapple, Steve Anthony; John, Maya Jacob ( Scrivener Publishing , 2018 , Article)This work reports on the effect of commercial expandable graphite (EG) on the flammability and thermal decomposition properties of PLA-starch blend. The PLA-starch/EG composites were prepared by melt-mixing and their ...
