Correlação entre morfologia, percolação elétrica e propriedades mecânicas de compósitos da blenda PLA/PBS com grafite expandido
(Universidade Federal de São Carlos, 2013-12-06)
In recent years, researchers from industry and universities have focused
their interests in polymer nanocomposites, especially in multifunctional
composites. The composites made from nano expanded graphite ( nGE ) ...
Desenvolvimento de compósitos biodegradáveis a partir de amido termoplástico e fibras vegetais
(Universidade Federal de São Carlos, 2011-09-16)
This project had as main objectives to obtain and to develop new and biodegradable composites from renewable sources using a thermoplastic starch (TPS) matrix reinforced with different amounts of natural fibers, acuri, ...
Avaliação do reprocessamento de copolímero SAN através de moldagem por injeção
(Universidade Federal de São Carlos, 2011-06-30)
The main objective of this work was to study the reprocessing of copolymer SAN through injection molding and its influence on the mechanical, thermomechanical and optical behavior of that copolymer. Mechanical properties, ...
Durabilidade mecânica de compósitos de polipropileno com reforço híbrido de fibra de coco e talco
(Universidade Federal de São Carlos, 2012-08-13)
The use of natural fibers, as possible alternative reinforcement for synthetic fibers such as glass fibers, in polymer composites meets the requirement for development of new materials with environmentally sustainable ...
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)

(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 ...
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 ...
