Phasenstruktur, molekulare Konformation und Fließverhalten flüssigkristalliner Polymere
… unter Scherung zwischen Shear-Alignment (stabile Direktororientierung nahezu in Fließrichtung) und Tumbling (keine stabile Direktororientierung, Ausbildung einer Polydomänenstruktur) unterschieden. Mit zunehmendem Anteil an Struktureinheiten mit langem Spacer wird ein …

Implications of Nanofiber Length and Polydispersity on Flow Alignment
… a compelling system for studying flow-induced alignment, a key factor in designing bio-based materials with tailored properties. While structural properties of PNFs are at rest well-characterized, comprehensive insight into their colloidal behavior, shear response, and alignment mechanisms …

Template-based control for bottom-up nanostructures - multilayer block copolymer graphoepitaxy and masked ZnO nanowire growth
… thesis investigates templated control over the alignment and morphology of two bottom-up nanostructures, ZnO nanowires (NWs) and cylinder-forming block copolymers (BCPs). Despite material differences, we highlight their analogous nature by applying similar engineering principles to both - …

Self-assembled molecular nanomaterials and their applications
… these individual nanomaterials can undergo shear alignment to form hierarchically ordered macroscopic material that is mechanically flexible and stable in air. Furthermore, the enhanced intermolecular cohesion also provides an alternative pathway to circumvent the previously mentioned second …

Development of Sustainable Thermoplastic Elastomers
… compression molding. Large amplitude oscillatory shear was employed at a temperature below ODT to align the randomly oriented grains. The predominant orientation was determined to be hexagonally close-packed spherical domains with the {0001} planes parallel to the shear plane, with a small …
