  • Accelerated photo-oxidation of Polyamide 11 nanocomposites under various clays nanofillers 
    Dehouche, Nadjet; Kaci, Mustapha; Focke, Walter Wilhelm; Van der Merwe, Liezel (Wiley, 2022-08)
    The effect of various clays nanofillers on the photo-oxidation of polyamide 11 (PA11) has been investigated by accelerated ultraviolet (UV) test up to 780 h. Organo-modified montmorillonite, halloysite nanotubes, and ...
  • A degradation study of polyamide 11/vermiculite nanocomposites under accelerated UV test 
    Kaci, Mustapha; Dehouche, Nadjet; Focke, Walter Wilhelm; Van der Merwe, E.M. (Elizabet Margaretha) (Wiley, 2019-12)
    Accelerated photooxidation under ultraviolet (UV) test of polyamide 11 (PA11) films filled with unmodified vermiculite clay at 5 wt% was investigated up to 600 h. Film samples of ~60‐μm thick were prepared by melt compounding ...
  • The effects of unmodified vermiculite on photooxidation of polyamide 11 nanocomposites under accelerated UV test 
    Kaci, Mustapha; Focke, Walter Wilhelm; Van der Merwe, E.M. (Elizabet Margaretha) (American Institute of Physics, 2018-07)
    The effects of unmodified vermiculite (UMVC) clay on the photooxidation of polyamide 11 (PA11) were investigated by accelerated UV test up to 600 h. The clay was incorporated to the polymer at a content ratio of 5 wt. %. ...
  • Flame retarding polyamide 11 with exfoliated vermiculite nanoflakes 
    Macheca, Afonso; Focke, Walter Wilhelm; Kaci, Mustapha; Panampilly, B.; Androsch, R. (Wiley, 2018-10)
    Polyamide 11‐based bionanocomposites were prepared by melt compounding with 10 wt% clays of different chemistry and morphology. This included vermiculite nanoflakes obtained by consecutive thermal and ultrasonic exfoliation ...
  • Stiffening mechanisms in vermiculite-amorphous polyamide bio-nanocomposites 
    Macheca, Afonso; Focke, Walter Wilhelm; Muiambo, H.F. (Herminio Francisco); Kaci, Mustapha (Elsevier, 2016-01)
    Sub-micron thick flakes were obtained by sonication of vermiculite that was first exfoliated by either thermal shock or chemical treatment with hydrogen peroxide. Dimer fatty acid polyamide nanocomposites with a mixed ...
  • Tribological and mechanical properties of polyamide-11/halloysite nanotube nanocomposites 
    Sahnoune, Mohamed; Kaci, Mustapha; Taguet, Aurélie; Delbé, Karl; Mouffok, Samir; Abdi, Said; Lopez-Cuesta, José-Marie; Focke, Walter Wilhelm (De Gruyter, 2019-01)
    This article reports some morphological, tribological, and mechanical data on polyamide-11(PA11)/halloysite nanotube (HNT) nanocomposites prepared by melt-compounding. HNTs extracted from the Djebel Debbagh deposit in ...
