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 ...
Estruturação da blenda de PP/PVMS na presença de nanopartículas
(Universidade Federal de São Carlos, 2014-09-26)
Blends technology get by mechanical blend extends the range of polymer properties and makes it possible to fit them for specific applications. The performance and the mechanical properties of immiscible polymer blends are ...
Desenvolvimento e caracterização de nanocompósitos de blendas de PA6/AES compatibilizadas com copolímero acrílico
(Universidade Federal de São Carlos, 2014-03-31)
Toughened polyamide 6 (PA6) nanocomposites were obtained by incorporation of acrylonitrile-EPDM-styrene (AES). As compatibilizing agents was used the copolymer methyl methacrylate-anhydride (MMA-MA). The effect of the ...
Avaliação de sistemas compatibilizantes nas correlações entre processamento e propriedades térmicas, mecânicas e de transporte em nanocompósitos de blenda HDPE/LLDPE e OMMT
(Universidade Federal de São Carlos, 2012-04-11)
Polyolefin nanocomposites have attracted significant technological and scientific interest due to the possibilities of improvements in thermal, mechanical and barrier properties. However, the hydrophobic nature of polyolefins ...
Desenvolvimento de blendas nanoestruturadas SAN/PBT modificadas com copolímeros acrílicos reativos
(Universidade Federal de São Carlos, 2012-08-02)
In this work we have obtained transparent nanoblends of poly(styrene-coacrylonitrile) (SAN) as matrix and poly(butylene terephthalate) as a nanometric phase. The materials were produced by means of reactive mixing in a ...
Desenvolvimento e caracterização de blendas Poli(tereftalato de etileno) - PET/ Poli(naftalato de etileno)- PEN
(Universidade Federal de São Carlos, 2000-03-03)
The scientific and technological development of food packaging polymers has increased considerably over the last years, especially in relationship to packaging for beverages such as carbonated soft drinks and beer. As for ...
Estudos microrreológicos da blenda PBT/SAN.
(Universidade Federal de São Carlos, 2006-09-22)
This work was motivated by the need of a better understanding of the
microrheological characteristics of polybutylene terephthalate, PBT, polymer
blends, such as the matrix phase PBT and the styrene-acrylonitrile, SAN
copolymer ...
Modificação do Poli(hidroxibutirato) PHB com nucleantes e com o copolímero (etileno-co-acetato de vinila) - EVA
(Universidade Federal de São Carlos, 2008-03-19)
In this work, we sought to modify PHB, processing it in the melted state, and to
evaluate the effect of the modifications on its mechanical properties and
biodegradation characteristics. The following systems were therefore ...
Monitoramento em tempo real da morfologia na extrusão da blenda polimérica polipropileno/ nylon 6.
(Universidade Federal de São Carlos, 2006-09-01)
The aim of this work is to assess in real time the morphological
parameters of polypropylene and polyamide 6 blends during the extrusion
process. An optical detector based on the visible light transmitted and extinction
principle ...
