Preparation and characterization of soy lecithin-modified bentonites
(Elsevier Science, 2016-04-14)
In this work, a study of exchange of soy lecithin, a natural product, in bentonite was performed in order to synthesize bio-organoclays. The effects of initial amount of modifier and reaction time were studied at a fixed ...
Mechanical and thermomechanical properties of polyamide 6/Brazilian organoclay nanocomposites
(Associação Brasileira de Polímeros, 2016)
Enhancement of chloroprene/natural/butadiene rubber nanocomposite properties using organoclays and their combination with carbon black as fillers
(2021-04-01)
Organoclay nanoparticles (Cloisite® C10A, Cloisite® C15) and their combination with carbon black (N330) were studied as fillers in chloroprene/natural/butadiene rubber blends to prepare nanocomposites. The effect of filler ...
Ablative Properties of Polyurethanes Reinforced with Organoclay
(John Wiley & Sons Inc., 2020-01)
Ablation resistance and mechanical properties of polyurethanebased composites containing different amounts (up to 5 wt%) of organoclay were correlated with the morphological characterization. The crosslinking density of ...
Selective sorption of mercury(II) from aqueous solution with an organically modified clay and its electroanalytical application
(Taylor & Francis Inc, 2006-01-01)
The organo-clay used in this work was prepared from a Na-montmorillonite (Wyoming-USA deposit) by treatment with water solution of hexadecyltrimethylammonium cations. As organo-clays exhibit strong sorptive capabilities ...
Morphological Characterization of Brazilian Organ Clays Using AFM and SEM Studies
(2013-05)
A combination of SEM (Scanning Electron Microscopy) and AFM (Atomic Force Microscopy) techniques was used to characterise the morphology of Brazilian montmorillonites before and after intercalation of some organic compounds. ...
Effect of the organoclay preparation on the extent of intercalation/exfoliation and barrier properties of polyethylene/PA6/montmorillonite nanocomposites
(Wiley, 2010-11)
Nanocomposites of HDPE matrix and 3 wt % organoclay/PA6 discontinuous phase were prepared in a mixer chamber. These nanocomposites of organoclay, PA6, and HDPE were characterized by X-ray diffraction, scanning electron and ...
Nanocompósito de PP/PP-g-AM/argila organofílica: processamento, propriedades mecânicas, termo-mecânicas e de permeação de gás
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Química - PPGQ, 2009-08-28)
The aim of present work was developing nanocomposites of polypropylene (PP) with organoclay (MMT) in the presence of a compatibilization agent (PP-g-MA) in the melt state. The masterbatch of PP-g-MA and organoclay was ...
PLA and Organoclays Nanocomposites: Degradation Process and Evaluation of ecotoxicity Using Allium cepa as Test Organism
(2013-07-17)
In this study, nanocomposites of PLA and organoclays Cloisite 20A and Cloisite 30B were prepared by the melt intercalation method and the obtained samples were characterized by transmission electron microscopy (TEM). Since ...
