Resumo: The SAXS data were obtained at the STFC SRS at Daresbury UK and we thank Guenter Grossman for his help with the SAXS experiments. The microscopy was performed in the Centre for Advanced Microscopy at the University of Reading. The research work at IPL was supported by the Fundação para a Ciência e a Tecnologia (FCT) through the Project references: UID/Multi/04044/2013; PAMI-ROTEIRO/0328/2013 (No 022158), MATIS (CENTRO-01-0145-FEDER-000014-3362) and Project UC4EP.

We show that by introducing small quantities of a terpolymer, based on polyvinyl butyral we can switch the symmetry axis of the final lamellar orientation from parallel to perpendicular to the melt flow direction. During shear flow of the polymer melt, the dibenzylidene sorbitol forms highly extended nanoparticles which adopt a preferred alignment with respect to the flow field and on cooling, polymer crystallisation is directed by these particles. The presence of the terpolymer, based on polyvinyl butyral, limits the aspect ratio of the dibenzylidene sorbitol (DBS) particles, such that the preferred orientation of the particles in the polymer melt changes from parallel to normal to the flow direction. The alignment of lamellar crystals perpendicular to the flow direction has important implications for applications such as scaffolds for tissue engineering and for barrier film properties.MDPIIC-OnlineMitchell, Geoffrey R.Olley, Robert H.2023-04-24T13:14:43Z20182018-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10400.8/8448engMitchell, G.R.; Olley, R.H.
