Understanding polymer nucleation by studying droplets crystallization in immiscible polymer blends
(Elsevier, 2023-01)
This Feature Article reviews our recent work on the nucleation and crystallization of finely dispersed semicrystalline polymeric droplets in immiscible matrices. Droplets dispersions can be used as a toolbox to investigate ...
Chemical Structure Drives Memory Effects in the Crystallization of Homopolymers
(ACS, 2020-06-11)
Although the study of melt memory has attracted much interest, the effect of polymer chemical structure on its origin has not been fully elucidated. In this work, we study melt memory effects by Differential Scanning ...
Peculiar self-nucleation behavior of a polybutene-1/ethylene random copolymer
(Wiley, 2021-07-31)
The self-nucleation behavior of a polybutene-1/ethylene random copolymer, P(B1-ran-E), which undergoes a complex crystal-crystal transition behavior, has been studied in detail. Similar to PE random copolymers, this material ...
Surface-enhanced nucleation in immiscible polypropylene and polyethylene blends: The effect of polyethylene chain regularity
(Elsevier, 2023-08)
In blends where polyethylene (PE) is the minor component dispersed in an isotactic-polypropylene (PP) matrix, an enhancement of the crystallization rate of PE was found when the crystallization temperature of the matrix ...
Disappearance of Melt Memory Effect with Comonomer Incorporation in Isodimorphic Random Copolyesters
(ACS, 2023-10)
Melt memory effects in polymer crystallization have attracted much attention in the past few years. Although progress has been made in understanding how the chemical structure of polymers can affect melt memory, there are ...
Fast successive self-nucleation and annealing (SSA) thermal fractionation protocol for the characterization of polyolefin blends from mechanical recycling
(Wiley, 2022-04-29)
The sorting stage of mechanical recycling of post-consumer polyolefins has severe challenges. Polypropylene (PP) is often contaminated with polyethylene (PE) and vice versa. To meet quality requirements, characterization ...
