  • Alkyl ammonium intercalation of Mozambican bentonite 
    Massinga, Pedro Horacio; Focke, Walter Wilhelm; De Vaal, Philip L.; Atanasova, Maria Todorova (Elsevier, 2010-07)
    Organo-bentonites containing quaternary ammonium surfactants were prepared using purified bentonite from the Boane deposit in Mozambique. The intercalation was effected by intimate mixing of the surfactants into a concentrated ...
  • EVA nanocomposites based on South African Koppies clay 
    Massinga, Pedro Horacio; Focke, Walter Wilhelm; Del Fabbro, Olinto; Radusch, Hans-Joachim (Wiley, 2014-09)
    South African Koppies bentonite was organo-modified with single tail and double tail alkyl ammonium cationic surfactants with the latter intercalated both below and above the clay CEC. Corresponding poly(ethylene-co-vi ...
  • Intercalating cationic surfactants in Koppies bentonite 
    Massinga, Pedro Horacio; Focke, Walter Wilhelm (Routledge, 2012-02)
    Single and double chain cationic surfactants were intercalated into Koppies bentonite. The state of the chains in the interlayers was probed using XRD, FTIR spectroscopy and thermogravimetric analysis (TG). The degree ...
  • Thermal properties of lauric- and stearic acid intercalated layered double hydroxides 
    Focke, Walter Wilhelm; Nhlapo, N.S. (Nontete Suzan); Moyo, Lumbidzani; Verryn, Sabine Marie Charlotte (Taylor & Francis, 2010)
    A commercial layered double hydroxide (LDH) with nominal composition [Mg0.689A10.311(OH)2](CO3)0.156.zH2O was intercalated with lauric and stearic acid using a surfactant-assisted method. X-ray diffraction, thermal analysis ...
