Development of PEG-PCL-based polymersomes through design of experiments for co-encapsulation of vemurafenib and doxorubicin as chemotherapeutic drugs
(2022-03-01)
Nanostructures for co-encapsulation of chemotherapeutic drugs have been widely studied for the last years due to its important advantages, e.g. improved bioavailability and cellular uptake, increased solubility of drugs, ...
Phase separation and segregation morphology of PCL/PS blends: quantitative effect of the crystallization temperature, composition and molecular weight of PS
(Wiley, 2016-11-21)
The phase diagrams for blends of semicrystalline poly(ecaprolactone)(PCL) with amorphous polystyrene (PS) were determined and it was noticed that when molecular weight increases, the critical composition diminishes while ...
Estudo de solubilidade do poliestireno (PS) e da policaprolactona (PCL) em diferentes solventes orgânicos
(Universidade Federal do Rio Grande do NorteBrasilUFRNEngenharia Química, 2015-11)
The polymer solubility is an important tool used in evaluating the characteristics of a polymer. This study aimed to analyse the polystyrene behaviour (PS) of three distinct molecular weights (Mw = 192, 280 and 350 kDa) ...
Generation of nanocomposites based on (PMMA-b-PCL)-grafted Fe2O3 nanoparticles and PS-b-PCL block copolymer
(Elsevier, 2014-09)
The aim of this work is to obtain a good dispersion of Fe2O3 magnetic nanoparticles into a PS-b-PCL diblock copolymer. For this purpose nanoparticles have been modified in their surface by grafting a PMMA-b-PCL block ...
Policaprolactona y polimierización por apertura de anillo; propiedades, métodos de síntesis y aplicaciones
(Universidad de los AndesQuímicaFacultad de CienciasDepartamento de Química, 2021)
Debido a la sobreproducción de plásticos sintéticos (Ps) hechos a partir de polímeros no biodegradables se ha presentado una problemática de contaminación a nivel mundial que ha logrado afectar a la mayoría de los ecosistemas. ...
Influence of amorphous block on the thermal behavior of well-defined block copolymers based on e-caprolactone
(Springer, 2013-05)
In this work, we studied the thermal characterization of block copolymers based on ε-caprolactone. The copolymers were obtained by anionic polymerization techniques, using different co-monomers such as styrene (S) and ...
Controlled One-Pot Synthesis of Polystyrene-block-Polycaprolactone Copolymers by Simultaneous RAFT and ROP
(Wiley, 2013-08)
A convenient one-pot method for the controlled synthesis of polystyrene- block -polycaprolactone (PS- b -PCL) copolymers by simultaneous reversible addition?fragmentation chain transfer (RAFT) and ring-opening polymerization ...
