Preparação e caracterização de nanocompósitos de LDPE e LDPE/EVA com partículas de Ag/TIO2 para aplicações antimicrobiais
(Universidade Federal de São Carlos, 2009-10-02)
This study investigated the use of a charger inorganic (titanium dioxide) as a support for silver nanoparticles and evaluated the use of material obtained as filler in polymer for antimicrobial application.Silver ...
Obtenção de nanocompósitos de poliamida 6 / argila nacional com diferentes agentes compatibilizantes
(Universidade Federal de São Carlos, 2005-09-01)
The formation of nanocomposites well exfoliated is dependent of several factors, like organic treatment with appropriate ammonium quaternary salts to promote adequate interaction between polymer and clay. The objective of ...
Preparação de argilas organofílicas para o desenvolvimento de nanocompósitos a partir de compostos de PVC plastificado
(Universidade Federal de São Carlos, 2009-12-15)
Nanocomposites of Plasticized PVC with organoclays have a large potential to improve the thermal resistance of PVC as well as its flame retardancy. However, a great problem in the production of PVC nanocomposites is the ...
Monitoramento in-line da formação de nanocompósitos PP/MMT via intercalação no estado fundido
(Universidade Federal de São Carlos, 2008-08-04)
The aim of this work is to monitor in-line, using an optical detector fitted at the extruder die exit, the formation of PP/MMT nanocomposites during polymer melt compounding. The intensity of the detector´s signal is ...
Dispersão seletiva de argila montmorilonita em blendas poliméricas de PA6/ABS
(Universidade Federal de São Carlos, 2009-08-25)
For some applications toughening of polyamide is important. This can be accomplished through the addition of an elastomeric phase to the polyamide matrix with the drawback of a reduction in the stiffness and strength of ...
Influência das variáveis do processo de mistura na morfologia e propriedades finais de filmes tubulares de nanocompósitos de polietileno de alta densidade
(Universidade Federal de São Carlos, 2006-12-15)
Blown of films is one of the most important processes of polymers for packaging application. The final properties are strongly linked with the morphology developed during the processing. The relationship between process ...
