ABSTRACT Polymer deformation spans 7–10 orders of magnitude in length scales, making its analysis a significant challenge. Optical force probes (OFPs), functional molecular motifs polymer mechanochemistry, enable the study mechanical properties by undergoing force‐activated optical changes, such as absorption, fluorescence, or chemiluminescence. This review highlights OFPs integrated within materials, focusing on their properties, methods for elucidation, and insights they provide. Special...
Despite their technological relevance, the resistance of soft thermoplastic polyurethanes (TPU) to crack propagation in cyclic fatigue has never been investigated detail. In particular, a clear shortcoming literature for this class materials is lack connection between and large strain behavior that fundamental role defining material's propagation. We demonstrate here first time when strain-induced stiffening mechanism TPU (already observed deformation) combined with presence nonhomogeneous...
Strong, tough, and antibacterial hydrogels are promising in the fields of human motion detection wearable electronics. However, it remains challenging to reach ability without losing mechanical properties. In this work, strong tough Fe3+-sodium alginate/poly(acrylamide-co-acrylic acid)/Ag nanowire (Fe3+-SA/P(Am-co-Ac)/AgNWs) hydrogel with was facially prepared using multiple physical bonds. The superior properties ensured by double network matrix well-designed interface between AgNWs....
Cavitation under constrained tension is a critical failure phenomenon in rubber parts. For laboratory tests, strain constraints can be generated using disk‐shaped samples, that is, pancake specimens. Due to suppressed transverse contractibility, the dominating hydrostatic tensile stress, which highest center part of specimen, causes an internal process controlled by formation and growth cavities. Laboratory X‐ray microtomography (μCT) powerful tool monitor evolution cavity population...
Superlattice deformation in PbS quantum dot thin films introduced by uniaxial strain: In situ GISAXS study on the correlation of morphology and photoluminescence.
Abstract Two recently developed experimental devices for investigating soft matter deformation are presented. Both exploit the capabilities of a modern synchrotron beamline to enable advanced and highly precise materials-science experiments in which X-ray scattering is registered. The can be operated both monotonic as well cyclic mode implemented into at DESY , Hamburg (Germany). Hence, relevant parameters, such displacement, force temperature, recorded synchronously with individual...
The aim of this study is concentrated on the experimental investigation crack initiation during dynamic wear process and its correlation with fatigue growth reinforced rubber materials. analyzed compounds suitable for applications such as treads truck tires were based natural (NR) polybutadiene (BR). behavior has been studied using an own developed testing equipment gravimetric determination mass loss test specimen. Fatigue (FCG) analysis was performed under pulse loading in accordance real...
Abstract Advanced experimental techniques in terms of situ dilatometry and X‐ray microtomography as well microscopy have been used to investigate cavitation unfilled carbon black reinforced styrene‐butadiene rubber vulcanizates. The work introduces into the features multiaxial deformation damage behavior characterized by formation growth internal defects – so‐called cavities . Experimental evidence indicates that occurs vulcanizates subjected constrained tensile deformation, while number is...
The topical section "Advanced Testing of Soft Polymer Materials" focuses on highvalue manuscripts related to sophisticated characterization methods soft polymer materials.Due the increasing demands in application advanced technology not only everyday life but especially industrial applications and for reduction environmental footprint, it is necessary replace conventional materials by polymers with enhanced properties capabilities.In fact, manufacturers products as well suppliers processors...
Abstract Eine typische Verbindungstechnik für Glasstrukturen ist der laminierte Verbund mit weichen polymerbasierten Klebstoffen, wie Silikon. Infolge geometrischer Zwänge im laminierten Verbund, zeigen diese ein spezifisches mechanisches Verhalten: sich unter Deformation einstellende überhöhte Spannungsmehrachsigkeit kann zur Kavitation führen. Zur Beschreibung dieses Schädigungsmechanismus praxisrelevanten Bedingungen sind angepasste, innovative Prüfmethoden die In situ ‐Dilatometrie und...
