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 borracha termoplástica por vulcanização dinâmica. TPV-(NBR+PP)
(Universidade Federal de São Carlos, 2012-09-14)
The union of technology of thermoplastic and rubber has contributed to the development of thermoplastic elastomers (TPE), which was evidenced through the study of patents in TPE in the last 20 years, where Japan and the ...
Desenvolvimento de blendas poliméricas policarbonato/ poli (Tereftalato de Butileno) (PC/PBT) compatibilizadas e nanoestruturadas
(Universidade Federal de São Carlos, 2012-03-08)
The evaluation of addition of a random copolymer as compatibilizing and his effect in obtaining nanostructured morphology in blends composed by PC as matrix and PBT as dispersed phase, were investigated. The copolymercom ...
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 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 ...
Caracterização de poli(hexametileno biguanida) e suas blendas com poli(álcool vinílico)
(Universidade Federal de São Carlos, 2012-07-31)
In this study, the physical-chemical characterization of poly(hexamethylene biguanide) hydrochloride, PHMB, was performed. It is a low molecular weight synthetic polymer with a broad-spectrum biocidal activity, widely used ...
