Promotion of self-nucleation with latent Form I nuclei in polybutene-1 and its copolymer
(American Chemical Society, 2018-08-02)
The formation of Form I nuclei of polybutene-1 (PB-1) and its copolymer with polyethylene (PB1-ran-PE) has been studied by means of modified self-nucleation protocols. Even when the self-nucleation temperature was high ...
Crystallization of isodimorphic aliphatic random copolyesters: pseudo-eutectic behavior and double-crystalline materials
(Elservier, 2018-02-28)
Isodimorphic random copolyesters are intriguing polymeric materials that can crystallize in their entire composition range, despite the random distribution of comonomer units along their chains. This behavior stems from ...
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 ...
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 ...
Residual alignment and its effect on weld strength in material-extrusion 3D-printing of polylactic acid
(Elsevier B.V, 2020-06-30)
Gaining a molecular understanding of material extrusion (MatEx) 3D printing is crucial to predicting and
controlling part properties. Here we report the direct observation of distinct birefringence localised to the ...
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 ...
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 ...
Nucleation modalities in poly(lactide), poly(butylene succinate) and poly(ε-caprolactone) ternary blends with partial wetting morphology
(John Wiley & Sons, Inc., 2020-08-17)
Ternary biodegradable polymer blends of poly(lactic acid) (PLA), poly(butylene succinate) (PBS), and poly(ε‐caprolactone) (PCL) with the composition 45/10/45 wt% and exhibiting partial‐wetting morphology were prepared. In ...
Nucleation of poly(lactide) partially wet droplets in ternary blends with poly(butylene succinate) and poly(ε-caprolactone)
(ACS, 2020-02-25)
This work presents the first investigation on the crystallization behavior of partially wet droplets in immiscible ternary blends. Poly(lactide), poly(ε-caprolactone), and poly(butylene succinate) (PLA, PCL, and PBS, ...
