Obtenção e caracterização de nanocompósitos de poli(cloreto de vinila): plastisol com argila
(Universidade Federal de São Carlos, 2011-03-03)
This project aims to study the effect of adding nanoparticles in the plastisol of poly(vinyl chloride) microsuspension. The influence of two different types of nanoclay, sodium montmorillonite and organophilic montmorillonite ...
Estudo de blenda polimérica PET/PE aplicado na reciclagem de aparas de filmes multicamadas
(Universidade Federal de São Carlos, 2013-12-18)
The main objective of this work was to analyze the viability of the recycling of post-industrial packaging scraps, compounded by multilayer laminated films of PET-HDPE, for production of polymer blends with good ...
Obtenção de estruturas de nanocompósitos poliméricos híbridos condutores
(Universidade Federal de São Carlos, 2013-03-28)
In this work, hybrid electrical conductive nanocomposites structures with potential to be applied in conductive and electrostatic dissipative devices were obtained. Such structures were produced by combining two types of ...
Modificação química de poli(ácido láctico) com anidrido maleico por processamento reativo
(Universidade Federal de São Carlos, 2014-08-18)
The chemical modification of PLA with maleic anhydride by reactive processing and the extent of reaction and degradation reactions, were studied. Routes of grafting reaction of maleic anhydride in PLA were evaluated. Dicumyl ...
Durabilidade de polietileno em vinhaça quente e fresca em usina de açúcar e álcool
(Universidade Federal de São Carlos, 2013-12-10)
Geomembranes are polymeric sheets widely used in vinasse ponds to prevent contamination of soil. Long-term durability is expected, since failure can result in environmental impact. Smooth black commercial geomembranes and ...

(Universidade Federal de São Carlos, 2013-05-10)
In this work its was investigated the influence of the processing on the electrical and dielectric properties of nanostructured polymeric systems obtained by differents techniques. The morphology and structure of the ...
Aplicação de estruturas zeolíticas de imidazólio (ZIFs) no desenvolvimento de membranas de matriz mista para separação de gases
(Universidade Federal de São Carlos, 2012-12-13)
Mixed matrix membranes based on a glassy polymer and a zeolite with organic character were developed, in order to evaluate whether the organic character of the ZIF-8 would favor its incorporation in the polymer matrix as ...
Estudo da influência de cargas minerais e amido na biodegradação do PLA
(Universidade Federal de São Carlos, 2010-05-31)
Fossile fuel-produced plastics, once consumed and incorrectly
discharged into the environment, will end up as short-term non-degradable
residues and will contribute to global pollution. For this reason, the use of
polymers ...
Desenvolvimento de nanoblendas poliméricas PMMA/SAN
(Universidade Federal de São Carlos, 2012-08-03)
The motivation for this work was the idea that nanoblends are fundamentally dependent on the high interaction between the phases in the mixture. The strategy adopted in this study was based on the use of two polymers that ...
Reciclagem química de PET proveniente de filtros industriais pós-consumo
(Universidade Federal de São Carlos, 2006-03-10)
The PET filter bag is used in the separation of the particulates materials of the gas produced in the aluminum industry. It had been submitted a chemical recycling. Almost industries make the disposal of these materials ...
