Polyethylene/sepiolite fibers. Influence of drawing and nanofiller content on the crystal morphology and mechanical properties
(Wiley, 2014-05)
The influence of sepiolite content (1, 2, and 3 wt%) and successive drawing steps on the final properties of polyethylene/sepiolite nanocomposite fibers are reported. Particularly the effects of these variables on ...
Morphology, flexural, and thermal properties of sepiolite modified epoxy resins with different curing agents
(Pergamon-Elsevier Science Ltd, 2006-11)
A bisphenol A-based epoxy resin was modified with 5 wt% organically modified sepiolite (Pangel B40) and thermally cured using two different curing agents: an aliphatic diamine (Jeffamine D230, D230) and a cycloaliphatic ...
Polyethylene/Sepiolite Nanocomposites: Structure/Properties/Processing Relationship
(Nova Science Publishers, 2015)
Polyethylene (PE) - sepiolite nanocomposites are very interesting materials because they combine their properties in a synergetic manner. Chemically, sepiolite is a hydrated magnesium silicate with the ideal formula ...
Processing and final properties improvement of polyolefin-sepiolite and carbon nanofibre nanocomposites
(Wiley, 2011-03)
In this work polypropylene (PP) nanocomposites with different nanofillers (sepiolites and carbon nanofibres) have been produced, processed by injection moulding and fibre spinning and analyzed in terms of mechanical ...
Structured catalysts containing Co, Ba and K supported on modified natural sepiolite for the abatement of diesel exhaust pollutants
(Elsevier Science Sa, 2010-03)
Natural sepiolite-supported catalysts, structured as highly porous ceramic discs were investigated for their application in diesel exhaust after treatment. Catalysts containing cobalt, potassium and barium, which are active ...
Comparative analysis of crystallization behavior induced by different mineral fillers in polypropylene nanocomposites
(SAGE Publications, 2020-06-04)
A comparative analysis of crystallization behavior induced by several mineral fillers in polypropylene nanocomposites was performed. Morphological changes and thermal properties of nanocomposites were evaluated, considering ...
Supercritical CO2-assisted impregnation of LDPE/sepiolite nanocomposite films with insecticidal terpene ketones: Impregnation yield, crystallinity and mechanical properties assessment
(Elsevier Science, 2017-06)
In this contribution, supercritical CO2-assisted impregnation of LDPE/sepiolite nanocomposite films with two insecticidal terpene ketones (thymoquinone and R-(+)-pulegone) is investigated, as a strategy to enhance the ...
