PC-SAFT equation: A predictive tool to determine experimental conditions for polymer blend demixing
(Taylor & Francis, 2009-08-06)
The perturbed-chain statistical associating fluid theory equation of state (PC-SAFT) was applied to predict the phase behavior of polymer solutions in order to determine the pressure - temperature region for the high ...
Synthesis and characterization of dendronized polymers
(Wiley, 2007-11)
This research aims at the synthesis of several dendrons with different functional groups on their surface, and their use as functionalizing agents of synthetic polymers. Two principal products were synthesized and ...
Kinetics and binding properties of cloramphenicol imprinted polymers
(Elsevier Science, 2007-04)
Molecularly imprinted polymers (MIPs) are easily obtained by a non-covalent approach through the copolymerisation of suitable functional monomers and cross-linkers in the presence of the print molecule. Removal of the ...
Thermo-sensitive polymers in medicine: A review
(Pergamon-Elsevier Science Ltd, 2019-08)
A wide variety of smart polymer systems such as thermosensitive polymers (TSPs)have been developed and applied mimicking nature. TSPs are a class of macromolecules that exhibit bio-inspired behavior and have various ...
Polymer blend latex films: Miscibility and polymer diffusion studied by energy transfer
(Elsevier, 2008-04)
Fluorescence non-radiative energy transfer experiments were used to study latex blend films composed of high molar mass poly(butyl acrylate-co-methyl methacrylate) (PBA-co-MMA) and much lower molar mass PBA-co-MMA latex ...
Reversible modulation of the redox activity in conducting polymer nanofilms induced by hydrophobic collapse of a surface-grafted polyelectrolyte
(Academic Press Inc Elsevier Science, 2018-05)
We present the covalent modification of a Pani-like conducting polymer (polyaminobenzylamine, PABA) by grafting of a polyelectrolyte brush (poly [2-(methacryloyloxy)-ethyl-trimethylammonium chloride], PMETAC). As PABA has ...
Drag reduction by polymer additives from turbulent spectra
(American Physical Society, 2010-12)
We extend the analysis of the friction factor for turbulent pipe flow reported by G. Gioia and P. Chakraborty [Phys. Rev. Lett. 96, 044502 (2006)]10.1103/PhysRevLett.96.044502 to the case where drag is reduced by polymer ...
Morphology-dependent photophysical properties of Poly-4-vinylpyridine polymers containing –Re(CO)3 (N^N)+ pendants
(Centro de Estudios sobre Ciencia, Desarrollo y Educación Superior, 2020-03)
We review the morphological and the photophysical properties of several inorganic polymers that can be prepared from poly-4- vinylpyridine (P4VP). These polymers contain –Re(CO)3 (N^ N)+ pendants attached to their backbone ...
Thermodynamic analysis of a polymerization-induced phase separation in nanoparticle-monomer-polymer blends
(American Chemical Society, 2007-10-04)
We perform a thermodynamic analysis of the polymerization-induced phase separation in nanoparticle-monomer-polymer blends using a simple model recently proposed by Ginzburg (Macromolecules 2005, 38, 2362). The model was ...
Routes for nanoparticle translocation through polymer-brush-modified nanopores
(IOP Publishing, 2018-06)
This work presents a theoretical study of the translocation routes of nanoparticles through polymer-brush modified nanopores. The calculations were performed with a molecular theory that explicitly accounts for the shape, ...
