Effects of thermal treatment on phase transitions and on the mechanical relaxation in poly(vinylidene fluoride)
(2002-12-01)
This work reports on the effects from thermal treatment in poly(vinylidene fluoride), PVDF, obtained with differential scanning calorimetry (DSC) and dynamic thermal analysis (DMA) measurements. It is shown that in successive ...
Synthesis, characterization and thermal behaviour of solid-state compounds of 4-methoxybenzoate with some bivalent transition metal ions
(2005-05-18)
Solid-state M-4-MeO-Bz compounds, where M stands for bivalent Mn, Co, Ni, Cu and Zn and 4-MeO-Bz is 4-methoxybenzoate, have been synthesized. Simultaneous thermogravimetry-differential thermal analysis (TG-DTA), differential ...
The effect of ionic strength on the structural organization of dioctadecyldimethylammonium bromide in aqueous solution
(Springer, 2004-01-01)
High-curvature and stabilized vesicles of dioctadecyldimethylammonium bromide (DODABr) can be formed spontaneously in aqueous electrolytic solution. It is shown by cryo-transmission electron microscopy that 5.0 mM DODABr ...
Short-chain di-ureasil ormolytes doped with potassium triflate: Phase diagram and conductivity behavior
(2003-01-01)
Di-urea cross-linked poly(oxyethylene)/siloxane hybrids, synthesized by the sol-gel process and containing a wide concentration range of potassium triflate, KCF3SO3, have been analyzed by x-ray diffraction and differential ...
Influence of the processing conditions and corona poling on the morphology of β-PVDF
(2005-12-01)
The α → β phase transformation of PVDF through the stretching process at different temperatures was investigated. The optimum stretching conditions were studied and characterised by infrared spectroscopy and differential ...
Thermoanalytical study of heavier trivalent lanthanides fumarates
(2013-08-01)
Solid-state heavier lanthanides fumarates compounds have been synthesized, and the compounds were characterized by employing simultaneous thermogravimetry and differential thermal analysis (TG-DTA), differential scanning ...
Methanol oxidation on PtRu/C electrocatalysts prepared by a microemulsion method
(2007-12-01)
PtRu/C nanocatalysts were prepared by a microemulsion method using different values of water/surfactant molar ratio in order to get different particle sizes. Crystallite sizes and structural properties were determined by ...
PBAT-PLA blends used in shopping bags: characterization by differential scanning calorimetry, raman spectroscopy and wide angle x-ray diffraction
(Associação Brasileira de PolímerosFlorianópolis, 2013)
In this work we have investigated the microscopical changes associated with the biodegradation in simulated soil (16 weeks) of poly (butylene adipate-coterephthalate) (PBAT) and poly(lactic acid) (PLA) blends by means of ...
