Polymer-bridged Nanofibrils in a High-molar-mass Polyester via Co-assembly of Benzenetricarboxamide End Groups and an Additive

John Christopher Plummer, Holger Frauenrath, Daniel Görl, Michael Alan Giffin

Benzenetricarboxamide (BTA) derivatives are versatile compounds widely employed as nucleating agents in commercial semicrystalline plastics and as supramolecular ligands in self-assembling telechelic polymer-based organogels, hydrogels, and bulk elastomers ...

Supramolecular Modifications of Semicrystalline Polymers

Michael Alan Giffin

Supramolecular interactions play an important role in defining the structure and the resulting mechanical properties of materials. For instance, interchain hydrogen-bonding in PAs gives them superior strength and stiffness in engineering materials, while t ...

Thermoplastic Toughening of a Semiaromatic Polyamide with an Amino-telechelic Polyethylene

John Christopher Plummer, Holger Frauenrath, Michael Alan Giffin

Semiaromatic polyamides are used for metal replacementin advancedengineering applications to reduce weight and improve efficiency,but their range of application is limited by their inherent lack ofductility and toughness. Here, we combined semiaromatic pol ...

Semiaromatic Polyamides with Re-Entrant Chain Folding Templated by "U-Turn" Repeat Units

Rosario Scopelliti, John Christopher Plummer, Farzaneh Fadaei Tirani, Holger Frauenrath, Bilal Özen, Julien Philippe Cretenoud, Michael Alan Giffin

Biopolymers often show deterministic chain folding templated by repeat unit sequences whose conformations are locked in by intramolecular interactions. In this work, we have used repeat units based on rigid anthracene or acridine scaffolds, which we refer ...
