Polyol preparation by liquefaction of technical lignins in crude glycerol

Muller, Louis C.; Marx, Sanette; Vosloo, Hermanus C.M. (Scrivener Publishing, 2017)

This work reports a study of polyol synthesis through liquefaction of technical lignins in crude glycerol by means of 1H and 31P NMR spectroscopy. The polyols are intended for preparation of polyurethane foam; thus, it is ...
Production of bio-degradable polyurethane foam from sugarcane bagasse and biodiesel-derived crude glycerine

Marx, Sanette; Odendaal, Wilmar; Williams, Anné; Vermeulen, Urban; Grobler, Anne; Muller, L.C. (ETA-Florence Renewable Energies, 2015)

As the threat of the depletion of fossil based fuels becomes more of a reality, there is a need to find alternative carbon sources for the production of a wide range of chemicals, polymers and plastics. One plastic that ...
Spectroscopic characterization and antimicrobial activity of nanoparticle doped cyclodextrin polyurethane bionanosponge

Leudjo Taka, Anny; Fosso-Kankeu, Elvis; Doyle, Bryan P.; Carleschi, Emanuela; Youmbi Fonkui, Thierry (Elsevier, 2020)

This study reports on the spectroscopic characterization and antimicrobial potency of polyurethane cyclodextrin co-polymerized phosphorylated multiwalled carbon nanotube-doped Ag-TiO2 nanoparticle (pMWCNT-CD/Ag-TiO2) ...
