Composition containing a polymer and an additive

John Christopher Plummer, Holger Frauenrath, Daniel Görl

The invention describes a composition containing a) a functionalized polymer (10) that comprises at least one polymer segment (13) and at least two polymer aggregating segments (11,12) capable of forming non-covalent bonds based on a supramolecular interac ...

Effect of surface modification of colloidal silica nanoparticles on the rigid amorphous fraction and mechanical properties of amorphous polyurethane-urea-silica nanocomposites

John Christopher Plummer, Nicolas Candau, Oguzhan Oguz, Stéphane Henri Florian Bernhard

Colloidal silica nanoparticles (NPs) modified with eight different silane coupling agents were incorporated into an amorphous poly(tetramethylene oxide)-based polyurethane-urea copolymer matrix at a concentration of 10 wt % (4.4 vol %) in order to investig ...

Polyamide material

John Christopher Plummer, Holger Frauenrath, Nicolas Candau, Sylvain Cyril Claude Galland

The invention relates to a polyamide material containing a polyamide as the matrix polyamide and fibrillar polyamide particles, wherein at least 10 vol.% of the fibrillar polyamide particles, based on the total volume of the fibrillar polyamide particles, ...

High-temperature copolyamides obtained by the efficient transamidation of crystalline-crystalline polyamide blends

Véronique Michaud, John Christopher Plummer, Holger Frauenrath, Sylvain Cyril Claude Galland

High-performance thermoplastic composites based on semiaromatic polyamides are prime candidates for metal replacement in lightweight structural applications. However, the low ductility and toughness of semiaromatic polyamides remain major obstacles to thei ...

Scaffold requirements for periodontal regeneration with enamel matrix derivative proteins

John Christopher Plummer, Laurent Mirko Dejace, Matteo Gregorio Modesto Marascio, Alessandra Apicella, Peter Fischer

Periodontitis affects the attachment of natural teeth, and infection or inflammation associated with periodontitis may affect peri-implant tissues. Enamel matrix derivative (EMD) proteins provide stimulation for self-regeneration of the damaged tissue when ...

Molecular dynamics simulations of the intrinsically disordered protein amelogenin

John Christopher Plummer, Matteo Gregorio Modesto Marascio, Alessandra Apicella, Vincenzo Colangelo

Amelogenin refers to a class of intrinsically disordered proteins that are the major constituents of enamel matrix derivative (EMD), an extract of porcine fetal teeth used in regenerative periodontal therapy. Modifications in molecular conformation induced ...

Liquid CO2 processing of solid polylactide foam precursors

John Christopher Plummer, Yonghoon Yoon

Diffusion of CO2 in polylactide was modelled by assuming the diffusion coefficient to depend on CO2 concentration, c, according to D[c]=D[0]exp[Ac], where D[0] and A are empirical constants, with the aim of optimizing impregnation of nominally amorphous an ...

Thermal mending in immiscible poly(epsilon-caprolactone)/epoxy blends

Véronique Michaud, John Christopher Plummer, Amaël Maximilien Cohades, Erica Manfredi

Blends of commercial epoxy monomer with a 4,4'-diaminodiphenylsulfone hardener and poly(epsilon-caprolactone) (PCL) were evaluated for their potential as a self-healing matrix for fiber-reinforced composites, based on their room temperature toughness and s ...

The Influence of Arginine on the Response of Enamel Matrix Derivative (EMD) Proteins to Thermal Stress: Towards Improving the Stability of EMD-Based Products

John Christopher Plummer, Matteo Gregorio Modesto Marascio, Alessandra Apicella, Raffaele Mezzenga, Peter Fischer

In a current procedure for periodontal tissue regeneration, enamel matrix derivative (EMD), which is the active component, is mixed with a propylene glycol alginate (PGA) gel carrier and applied directly to the periodontal defect. Exposure of EMD to physio ...

Solid heat-expandable polylactide-poly(methyl methacrylate) foam precursors prepared by immersion in liquid carbon dioxide

John Christopher Plummer, Yonghoon Yoon

Solid heat-expandable foam precursors were prepared by impregnating melt-blended poly(d,l-lactide) (PDLLA)-poly(methyl methacrylate) (PMMA) blends with liquid carbon dioxide (CO2). The phase behavior of these blends was strongly dependent on the processing ...
