Compatibility and epitaxial crystallization between Poly(ethylene) and Poly(ethylene)-like polyesters
Pepels, Mark P. F.; Kleijnen, Rob G.; Goossens, Johannes G. P.; Spoelstra, Anne B.; Tandler, Renate; Martens, Hans; Soliman, Maria; Duchateau, Rob
This work describes the phase behavior of blends of ‘polyethylene-like’ polypentadecalactone (PPDL) and polyethylene. Blends of high-density polyethylene (HDPE) and PPDL were shown to be immiscible at the onset of crystallization of polyethylene, resulting in phase-separated morphologies. However, epitaxial crystallization of PPDL onto the HDPE crystals was observed by transmission…

Double Networks Based on Amphiphilic Cross-Linked Star Block Copolymer First Conetworks and Randomly Cross-Linked Hydrophilic Second Networks
Rikkou-Kalourkoti, Maria; Kitiri, Elina N.; Patrickios, Costas S.; Leontidis, Epameinondas; Constantinou, Marios; Constantinides, Georgios; Zhang, Xiaohan; Papadakis, Christine M.
This study presents the preparation and characterization of double networks (DN) based on a first amphiphilic polymethacrylate conetwork (APCN) and a second polyacrylamide network. The APCN first network comprised interconnected “in–out” star copolymers of 2-(dimethylamino)ethyl methacrylate (DMAEMA, hydrophilic ionizable monomer) and 2-ethylhexyl methacrylate (EHMA, hydrophobic comonomer) or…

Semifluorinated alkanes and alkanes: A phase study of the perfluorohexyloctane – Tetradecane system
Runnsjö, Anna; Kocherbitov, Vitaly; Graf, Gesche; Pettigrew, Anthony; Scherer, Dieter; Mortensen, Kell; Engblom, Johan
The binary system perfluorohexyloctane (F6H8)–tetradecane (C14) was investigated in order to increase understanding of interactions of semifluorinated alkanes (SFAs) with hydrophobic molecules. The thermal phase behavior for F6H8 and C14 and their mixtures was determined using DSC. The activity coefficients for both components in the mixtures were calculated and Gibbs…
Interaction of Artepillin C with model membranes
Pazin, Wallance Moreira; Olivier, Danilo da Silva; Vilanova, Neus; Ramos, Ana Paula; Voets, Ilja Karina; Soares, Ademilson Espencer Egea; Ito, Amando Siuiti
Green propolis, a mixture of beeswax and resinous compounds processed by Apis mellifera, displays several pharmacological properties. Artepillin C, the major compound in green propolis, consists of two prenylated groups bound to a phenyl group. Several studies have focused on the therapeutic effects of Artepillin C, but there is no…
Nucleation and mechanical enhancements in polyethylene-graphene nanoplate composites
Bourque, Alexander J.; Locker, C. Rebecca; Tsou, Andy H.; Vadlamudi, Madhavi
Graphene nanoplatelets (GNP) dispersed in high-density polyethylene (HDPE) were found to significantly enhance nucleation of PE crystallization, and thermal/mechanical properties of HDPE-GNP nanocomposites. Excellent dispersion of GNPs was achieved by combining solution blending and twin-screw extrusion homogenization. The dispersion state was confirmed by bimodal AFM and also by the resulting…
