PLA and Montmorilonite Nanocomposites: Properties, Biodegradation and Potential Toxicity
(2013-09-01)
The concern related to solid waste increases efforts to develop products based on biodegradable materials. At present, PLA has one of the highest potentials among biopolyesters, particularly for packaging. However, its ...
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 ...
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 ...
Voltammetry of mercury (II) based on an organo-clay modified graphite electrode
(2008-11-17)
Organo-clay complex of ligand-hexadecyltrimethylammonium with montmorillonite was made for the purpose of application as a preconcentration agent in a chemically modified carbon paste electrode for determination of mercury ...
Study of an organically modified clay: Selective adsorption of heavy metal ions and voltammetric determination of mercury(II)
(Elsevier B.V., 2006-01-15)
In this work, a hydrophilic clay, Na-montmorillonite from Wyoming, USA, was rendered organophilic by exchanging the inorganic interlayer cations for hexaclecyltrimethylammonium ions (HDTA), with the formulae of ...
Compatibilization mechanism induced by organoclay in PMMA/PS blends
(Journal Rheology Amer Inst Physics, 2017)
In this work, the effect of adding organoclay (Cloisite 20A) to a poly(methyl metacrylate) (PMMA)/polystyrene (PS) blend was evaluated in order to understand the compatibilization mechanism taking place. The blend morphology ...
Influence of mixing protocol on the morphology and mechanical properties of PP/SEBS/MMT and PP/SEBS/PPgMA/MMT blends
(2018)
© 2018 Elsevier LtdPP/SEBS blends containing MMT and MMT/PPgMA were obtained by extrusion using different mixing protocols. Specimens were subjected to mechanical testing (tensile, flexural and impact tests) and blend ...
Evaluation of the role of an ionic liquid as organophilization agent into montmorillonite for NBR rubber nanocomposite production
(Elsevier B.V., 2013-10-01)
In this work we have shown the preparation of montmorillonite (Na + Mt) co-intercalated with a quaternary ammonium salt (hexadecyltrimethylammonium - HDTMA) and an ionic liquid (IL) (1-methyl-3-octylimidazolium ...
Comportamento fotofísico do antraceno em sistemas micro-heterogêneos argila-surfactantes-íons metálicos
(Editora Unesp, 2009-12-01)
Argilas constituem uma classe de complexos micro-heterogêneos e podem ser utilizados como substrato para adsorção. O seu comportamento de sorção em fase sólida intensificada pela presença de surfactantes, argilas organofílicas, ...
Flowabitity of halogen-free flame retardant polymeric compositions
(2015)
Copyright © 2015, AIDIC Servizi S.r.l.In this work we have characterized one particular type of halogen-free flame retardant polymeric composition, used as sheath of electrical wires and cables. The five pure powders used ...
