Desenvolvimento de perfis extrudados de compósitos de polietileno de alta densidade com farinha de madeira
(Universidade Federal de São Carlos, 2009-12-17)
Polymer profiles extrusion shows some peculiarity due to the flow behavior of these materials during the processing. On the other hand, the profile die design and tooling has been more a result of professional s expertise ...
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 ...
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 ...
Influência da compatibilização interfacial seletiva nas propriedades mecânicas de compósitos híbridos ternários de PET/fibra de vidro/elastômeros olefínicos reativos
(Universidade Federal de São Carlos, 2009-09-25)
Poly(ethylene terephthalate) (PET) is a semi-crystalline thermoplastic widely used for packaging of aereted soft drinks, which makes the recycling of post-consumer PET material necessary to prevent the negative environmental ...
Processamento, caracterização e determinação do perfil de polarização do Poli(fluoreto de vinilideno)
(Universidade Federal de São Carlos, 2009-03-25)
This work characterized the ferroelectric polarization of the β-PVDF differentiating the individual contributions of the orientation and the crystalline phases in the remanent polarization of the PVDF. Those contributions ...
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 ...
