Correlation between Grafting Density and Confined Crystallization Behavior of Polyethylene Glycol Grafted to Silica
(American Chemical Society, 2019-02-06)
The interfacial interactions of polymer-nanoparticles have dramatical effects on the crystallization behavior of grafted polymers. In this study, methoxy polyethylene glycol (MPEG) (molecular weights 750, 2000 and 4000 g ...
Crystallization and morphology of poly (butylene succinate-ran-butylene azelate) random isodimorphic copolymers.
(2019-01-11)
En el presente trabajo se ha estudiado la estructura, morfología y cristalización de los copolímeros al azar PBS-ran-PBAz. Para ello hemos utilizado las técnicas de Calorimetría Diferencial de Barrido (DSC), Difracción de ...
Nucleation and crystallization in bio-based immiscible polyester blends
(Springer, 2019-08-21)
Bio-based thermoplastic polyesters are highly promising materials as they combine interesting thermal and physical properties and in many cases biodegradability. However, sometimes the best property balance can only be ...
How cyclic chain topology can reduce the crystallization rate of Poly(3- hexylthiophene) and promote the formation of liquid crystalline phases in comparison with linear analogue chains
(Royal Society of Chemistry, 2019-06-14)
We have studied how cyclic topology affects the crystallization and morphology of π-conjugated poly(3-
hexylthiophene) (P3HT) molecules by comparing linear and cyclic analogues for the first time, with three
different ...
The Effect of Titanium Dioxide Surface Modification on the Dispersion, Morphology, and Mechanical Properties of Recycled PP/PET/TiO2 PBNANOs
(MDPI, 2019-10-16)
Titanium dioxide (TiO2) nanoparticles have recently appeared in PET waste because of the introduction of opaque PET bottles. We prepare polymer blend nanocomposites (PBNANOs) by adding hydrophilic (hphi), hydrophobic (hpho), ...
Crystallization and morphology of multiphasic polymeric systems: random copolymers, nanocomposites and polymers with complex chain topologies.
(2019-01-29)
En el presente trabajo se caracterizaron térmica, estructural y morfológicamente diferentes sistemas multifásicos, entre los que se incluyen: (a) copoliésteres al azar con diferentes unidades repetitivas y comportamiento ...
Non-eutectic mixture organocatalysts (NEMOs): a step towardshigh temperature polymerizations.
(2019-09-16)
Los organocatalizadores han demostrado ser una alternativa eficiente y rentable a sus análogos organometálicos en muchos procesos de polimerización y hoy en día representan una herramienta invaluable en química de polímeros. ...
The origin of memory effects in the crystallization of polyamides: Role of hydrogen bonding
(Elsevier, 2019-12-23)
The effect of hydrogen bonding stability on the memory effects in the crystallization of long chain polyamides have been investigated by the self-nucleation calorimetric technique. Self-nucleation is characterized by three ...
