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 ...
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), ...
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 ...
How Confinement Affects the Nucleation, Crystallization, and Dielectric Relaxation of Poly(butylene succinate) and Poly(butylene adipate) Infiltrated within Nanoporous Alumina Templates
(ACS Publications, 2019-10-17)
This work describes the successful melt infiltration of poly(butylene succinate) (PBS) and poly(butylene adipate) (PBA) within 70 nm diameter anodic aluminum oxide (AAO) templates. The infiltrated samples were characterized ...
Tailoring the isothermal crystallization kinetics of isodimorphic poly (butylene succinate-ran-butylene azelate) random copolymers by changing composition
(Elsevier, 2019-10-07)
A detailed isothermal crystallization study of biobased and biodegradable isodimorphic poly (butylene succinate-ran-butylene azelate) random copolyesters (PBS-ran-PBAz) with a wide composition range has been carried out ...
Segmental Dynamics Govern the Cold Crystallization of Poly(lactic acid) in Nanoporous Alumina
(ACS Publications, 2019-09-04)
How segmental mobility influences the crystallization behavior of polymers in confined spaces is still not fully understood. In the present work, a systematic study of the segmental dynamics was carried out by dielectric ...
Organocatalyzed Polymerization of PET-mb-poly(oxyhexane) Copolymers and Their Self-Assembly into Double Crystalline Superstructures
(ACS Publications, 2019-08-30)
Double crystalline multi-block copolymers exhibit two well-defined melting temperatures associated with the two phases formed by their constituent blocks. The crystalline superstructure formed in these copolymers is complex ...
Crystallization and self-nucleation of PLA, PBS and PCL in their immiscible binary and ternary blends
(Elservier, 2019-06-13)
Three semicrystalline polyesters, poly(lactic acid), poly(caprolactone) and poly(butylene succinate) (PLA, PCL and PBS) were melt blended to prepare binary and ternary systems of selected compositions. In binary blends ...
