Uniaxial and Mixed Orientations of Poly(ethylene oxide) in Nanoporous Alumina Studied by X-ray Pole Figure Analysis
(American Chemical Society, 2018-11-16)
The orientation of polymers under confinement is a basic, yet not fully understood phenomenon. In this work, the texture of poly(ethylene oxide) (PEO) infiltrated in nanoporous anodic alumina oxide (AAO) templates was ...
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 ...
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 ...
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 ...
Unexpected Synthesis of Segmented Poly(hydroxyurea−urethane)s from Dicyclic Carbonates and Diamines by Organocatalysis
(ACS, 2018-07-17)
A complete study of the effect of different organocatalysts on the step-growth polyaddition of a five-membered
dicyclic carbonate, namely diglycerol dicarbonate, with a poly(ethylene glycol)-based diamine in bulk at 120 ...
Generating Triple Crystalline Superstructures in Melt Miscible PEO-b-PCL-b-PLLA Triblock Terpolymers by Controlling Thermal History and Sequential Crystallization
(WILEY-VCH, 2019-09-10)
The morphology, crystallization behavior and properties of multi-crystalline polymer systems based on triple crystalline biodegradable PEO-b-PCL-b-PLLA triblock terpolymers are reviewed. The triblock terpolymers, with ...
