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 ...
Effect of Nanoconfinement on the isodimorphic crystallization of Poly(butylene succinate-ran-caprolactone) Random Copolymers
(ACS, 2020-07-21)
In this paper, we study for the first time the effect of hard confinement on the isodimorphic crystallization of random copolyesters. A series of poly(butylene succinate-ran-caprolactone) samples encompassing the entire ...
Even-odd Effect in Aliphatic Polycarbonates with Different Chain Lengths: from Poly (hexamethylene carbonate) to Poly (dodecamethylene carbonate)
(ACS, 2020-12-17)
We have characterized a series of aliphatic polycarbonates synthesized by organocatalysis containing a variable number of methylene groups (nCH2) in their repeat units ranging from nCH2 = 6 to 12. The melting and crystallization ...
Crystallization, Orientation and Solid−Solid Crystal Transition of Polybutene‐1 Confined within Nanoporous Alumina
(ACS, 2020-07-31)
The effect of confinement on the crystallization, crystal orientation, and polymorphic crystal transition of bulk and infiltrated polybutene-1 (PB-1) within nanoporous alumina templates (AAO) were studied. After cooling ...
Effect of the crystallization conditions on the exclusion/inclusion balance in biodegradable poly(butylene succinate-ran-butylene adipate) copolymers
(ACS, 2020-07-14)
Biomedical applications of polymers require precise control of the solid-state structure, which is of particular interest for biodegradable copolymers. In this work, we evaluated the influence of crystallization conditions ...
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 ...
