Síntese de ligantes diimínicos para obtenção de complexos organocobalto(III) para polimerização radicalar mediada por cobalto
(Universidade Estadual Paulista (Unesp), 2017-02-22)
Neste trabalho objetivou-se a síntese e caracterização de oito complexos de cobalto(II) que fossem aptos a atuarem como agentes controladores na Polimerização Radicalar Mediada por Cobalto do monômero acetato de vinila. ...
Hybrid materials based on aluminum tungstophosphate or tungstosilicate as catalysts in anisole acylation
(Elsevier Science, 2008-04)
New hybrid materials were prepared by the immobilization of aluminum tungstophosphate or tungstosilicate in a polymeric blend formed by polyvinyl alcohol and polyethylene glycol by the freeze-thawing method. The salts ...
Controlling the generation of bilayer and multilayer vesicles in block copolymer/epoxy blends by a slow photopolymerization process
(Royal Society of Chemistry, 2017-09)
Vesicles are a highly attractive morphology to achieve in micellar dispersions of block copolymers (BCP) in epoxy thermosets due to the fact that small amounts can affect a large volume fraction of the matrix, a fact that ...
Dextrin-microencapsulated porphyrin - Luminescent properties
(BLACKWELL PUBLISHING, 2008)
Photophysical properties of porphyrins in aqueous solutions are strongly affected by aggregation. One possible solution to this problem is to encapsulate the porphyrin into polymeric spheres, to provide an environment where ...
Laserlike emission from silica inverse opals infiltrated with rhodamine 6G
(Elsevier B.V., 2005-07-15)
Monodisperse latex spheres were obtained by a surfactant free styrene polymerization method and used to obtain colloidal crystals by controlled centrifugation settling. Silica inverse opals were then prepared by using the ...
