Influência das variáveis do processo de mistura na morfologia e propriedades finais de filmes tubulares de nanocompósitos de polietileno de alta densidade
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEMCâmpus São Carlos, 2006-12-15)
Blown of films is one of the most important processes of polymers for packaging application. The final properties are strongly linked with the morphology developed during the processing. The relationship between process ...
Influência da geometria da nanocarga na estruturação, orientação e propriedades de filmes tubulares de nanocompósitos de PA6
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEM, 2012-06-13)
The structure and morphology of polymers and consequently their properties are dependent on the processing conditions. During the blown film process, high shear and elongational flows can induce a preferred orientation of ...

Desenvolvimento e caracterização de filmes tubulares de nanocompósitos de PEAD/EVA/argila organofílica
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEM, 2008-03-10)
In this work, the use of ethylene-vinyl acetate copolymer (EVA) in substitution to compatibility agents normally employed in the production of high density polyethylene (HDPE) nanocomposites (such as polyethylene grafted ...
Estudo das propriedades reológicas de nanocompósitos para a produção de filmes tubulares
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEM, 2008-07-08)
In this work, the use of rheological measurements in substitution or complementation to methods normally employed in the characterization of nanocomposites, such as X-ray diffraction (WAXS) and transmission electron ...
Template-based fluoroethylenepropylene piezoelectrets with tubular channels for transducer applications
(AMER INST PHYSICS, 2009)
We describe the concept, the fabrication, and the most relevant properties of a piezoelectric-polymer system: Two fluoroethylenepropylene (FEP) films with good electret properties are laminated around a specifically designed ...
Template-based fluoropolymer ferroelectrets with multiple layers of tubular channels
(Ieee, 2010-01-01)
Significant efforts are devoted to developing new ferroelectrets with well-controlled void distributions or uniform voids and with good long-term and thermal stability of the piezoelectricity. Here, we describe the concept, ...
Tubular-structured polypyrrole electrodes decorated with gold nanoparticles for electrochemical sensing
(Elsevier Science, 2018-03-01)
The electrosynthesis and characterisation of polypyrrole(PPy) films with a micro-tubular structure decorated with gold nanoparticles is described. The PPy films were characterised by means of voltammetric and electrochemical ...
