Effect of the doping medium on blends of polyurethane and polyaniline
(Elsevier B.V., 2001-03-15)
Flexible and free-standing films from blends of polyurethane, based on castor oil, and polyaniline were obtained with various compositions by casting. Significant increase on conductivity followed by a considerable decrease ...
Dielectric and pyroelectric properties of a composite of ferroelectric ceramic and polyurethane
(Springer, 2002-05-01)
Flexible piezo- and pyroelectric composite was made in the thin film form by spin coating. Lead Zirconate Titanate (PZT) ceramic powder was dispersed in a castor oil-based polyurethane (PU) matrix, providing a composite ...
Characterization of castor oil based polyurethane films prepared with N-methyl-2-pyrrolidinone as a solvent
(Wiley-Blackwell, 2005-10-15)
Molecular mobility in castor oil based polyurethane was investigated with thermally stimulated depolarization current (TSDC) measurements and alternating-current (ac) dielectric relaxation spectroscopy. Three peaks could ...
Preparation and characterization of the bacterial cellulose/polyurethane nanocomposites
(2013-02-12)
New nanocomposites based on bacterial cellulose nanofibers (BCN) and polyurethane (PU) prepolymer were prepared and characterized by SEM, FT-IR, XRD, and TG/DTG analyses. An improvement of the interface reaction between ...
Biodegradation of polyurethane derived from castor oil
(Associação Brasileira de Polímeros, 2008-09-01)
The aim of this research was to study the biodegradation of a polymer derived from castor oil, which is a renewable, natural material that is a practical alternative for the replacement of traditional polyurethane foams. ...
Mechanical adherence analysis of polyurethane and polyester commercial coatings over alder wood
(2021-09)
This study is the validation for a new method to introduce a new
color coating in the fabrication of electric guitars, before this, the
time for the validation was 20 to 25 days. This new validation reduced
the time to ...
Dynamic mechanical properties for polyurethane elastomers applied in elastomeric mortar
(Wiley-Blackwell, 2012-11-15)
Dynamic mechanical properties of a polyurethane (PU) elastomer and a mortar processed with the same elastomer (modified polytetramethylene ether glycol (PTMEG)) were studied. The results obtained showed that the liquid ...
