Blendas de PHBV e PCL para uso em dispositivos de osteossíntese
(Universidade Federal de São Carlos, 2010-12-15)
This study aimed to develop and characterize polymer blends using biodegradable and bioabsorbable polymers poly (hydroxybutyrate-co-valerate) PHBV with 12% valerate, and poly (ε-caprolactone) PCL, in order to make ...
Tenacificação de poli(ftalamida) (PPA) através de nanocompósitos com carbonato de cálcio e de blendas com copolímero estireno/etileno-butileno/estireno (SEBS)
(Universidade Federal de São Carlos, 2010-05-20)
This project aims the toughening of a high performance thermoplastic polyphthalamide (PPA). PPA resins is a good choice for special applications where the conditions are more severe than the ones an engineering thermoplastic ...
Análise sistêmica das massas de tamponamento para altos-fornos
(Universidade Federal de São Carlos, 2010-05-05)
The increase in the world steel production mainly observed in the last decade demanded a significant growth in the hot metal production through the blast furnace process. A key point in blast furnaces operation is related ...
Processamento de nanofibras de poliamida 66 / nanotubos de carbono de múltiplas camadas por eletrofiação
(Universidade Federal de São Carlos, 2010-03-26)
Nanocomposite fibers with polymer matrix have many applications, such as protective clothing, filtration and artificial blood vessels. Many of these applications require that the fiber has nanometric size due to some ...
Utilização da borracha natural no desenvolvimento de elastômeros termoplásticos
(Universidade Federal de São Carlos, 2010-05-28)
Dynamic vulcanization is a process of vulcanization of an elastomer during melt mixing with a thermoplastic. This process results in an elastomeric alloy material with the properties of a conventional thermoset rubber, but ...
