MECHANICALLY ROBUST BIOCOMPATIBLE POLYMERIC NETWORKS FOR REPETITIVE LOADING
Crosslinked biocompatible polymer networks offer unique potential for biomedical applications that demand high resilience under repetitive load-bearing conditions. However, conventional hydrogels often exhibit poor mechanical strength and irreversible damage under cyclic deformation, while …

High performance polymeric networks and thermoplastic blends: microwave versus thermal processing
Microwave processing of polymeric adhesives and composites offers great potential for future materials development. However, basic considerations need to be established which will allow the processing of polymeric systems, both as reactive thermosetting systems and as nonreactive thermoplastics. …

Deciphering how the viscoelastic properties of mussel-inspired metal-coordinate hydrogels dictate their adhesive and interfacial mechanics
… cross-links into various types of polymeric networks to improve their mechanical properties, particularly toughness, self-healing, and adhesion. However, there is not as much fundamental understanding of how the linear viscoelastic properties of these networks dictate adhesive …

Graphene/Oxide Interactions with Polymer Networks Modeled Using Molecular Dynamics
… dispersion of the graphene platelets within a polymeric network is critical to realizing these enhancements. Research has shown that achieving homogeneous dispersion of graphene platelets within PMCs is challenging as graphene is immiscible with most polymeric networks. This work used Molecular …

Synthesis and Characterization of Complex Polymer Topologies using Ring-Opening Metathesis Polymerization
… and electronic and transport substrates. Polymeric side chains are tightly grafted to a polymer backbone in these macromolecules. Bottlebrush polymers' densely bonded structure causes steric repulsion between nearby polymer chains, leading them to exhibit a chain-extended conformation. …

Netzwerkheterogenität und kooperative Bewegung: Untersuchung von Netzwerken unterschiedlicher Vernetzungsmechanismen mit dynamischer Lichtstreuung
Die Struktur von Netzwerken wird durch die Wahl der Netzwerkaufbaureaktion, der Ausgangsmoleküle und der Reaktionsbedingungen bestimmt. Es ist schwierig, wenn nicht gar unmöglich, geeignete Reaktionsparameter zu finden, die zum Aufbau homogener Netzwerkstrukturen führen. Die unterschiedliche …
