Silica/clay organo-heterostructures to promote polyethylene–clay nanocomposites by in situ polymerization
Two clay organo-heterostructures have been prepared and employed as fillers and catalyst supports for the development of polyethylene–clay nanocomposites. The new silica–clay organo-heterostructures have been obtained ...
Evaluation of modified silica nanoparticles in carboxylated nitrile rubber nanocomposites
Surface-modified silica nanoparticles have a plenty of applications, such as coatings, dyes or biomarkers, catalysts and encapsulated products. When modified with 3-(trimethoxysilyl)propyl methacrylate (SiO2-MPS) or covered ...
PREPARATION OF NANOCOMPOSITES BY IN SITU POLIMERIZATION
(Sociedad Chilena de Química, 2008)
Polyethylene/reduced graphite oxide nanocomposites with improved morphology and conductivity
The use of graphite and polyolefins as starting materials to prepare nanocomposites is convenient because both are inexpensive and have very different properties, one is conductive and the other is insulating. The formation ...
Comparison of the nanoparticles performance in the photocatalytic degradation of a styrene-butadiene rubber nanocomposite
Much has been talking about the advantages of polymeric nanocomposites, but little is known about the influence of nanoparticles on the stability of these materials. In this sense, we studied the influence of both oxides ...
Alkylammonium Alpo-kanemite As Support For Tuning Catalytic Activity Of Metallocene: In Situ Preparation Of Polyethylene Nanocomposites
(Elsevier Science BVAmsterdam, 2016)
Preparation and structural characterization of Zn and CeO2 nanocomposite materials as catalytic supports
Cerium(IV) and zinc(II) oxide nanocomposite powders (Zn-to-Ce atomic ratio between 0.5 and 2) as well as the pure oxideswere prepared by co-precipitation of cerium(III) and zinc(II) cations with oxalate (OC) or carbonate ...
Synthesis, characterization and properties of poly(propylene-1-octene)/graphite nanosheet nanocomposites obtained by in situ polymerization
Poly(propylene-1-octene)/graphite nanosheet (PPC8/GNS) nanocomposites with different comonomer and graphite nanosheet (GNS) contents were synthesized by in situ polymerization using metallocene catalyst. There was a ...
