Correlating the rheological and mechanical response of polyurethane nanocomposites containing hyperbranched polymers

Jan-Anders Edvin Maansson, John Christopher Plummer, Marlene Rodlert

Cast polyurethane thermosets have been modified with randomly oriented exfoliated and intercalated montmorillonite clay usinghyperbranched polymers (HBP) as reactive additives to promote dispersion of the clay platelets. The influence of the clay content o ...

Composites and methods for their production

Jan-Anders Edvin Maansson, Yves Leterrier, John Christopher Plummer, Marlene Rodlert

Intercalates and exfoliates formed from layered materials and dendritic polymers are disclosed, together with the uses of these materials, e.g. in producing composite materials. The dispersion of layered materials in a dendritic polymer matrix (hyperbranch ...

Scaffold requirements for periodontal regeneration with enamel matrix derivative proteins

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

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 ...

Mechanical integrity of dye-sensitized photovoltaic fibres

Jan-Anders Edvin Maansson, Yves Leterrier, John Christopher Plummer

The development of photovoltaic (PV) devices based on dye-sensitized TiO2-coated Ti fibers has opened up exciting possibilities for novel PV textile applications. The cohesion and adhesion of the TiO2 layer are identified as crucial factors in maintaining ...

Synthesis and photopolymerization of Tween 20 Methacrylate/N-vinyl-2-Pyrrolidone blend

Jan-Anders Edvin Maansson, Dominique Pioletti, Pierre-Etienne Bourban, John Christopher Plummer, Ana Borges de Couraça

Poly(oxyethylene 20 sorbitan) monolaurate (Tween® 20) methacrylates were synthesized by coupling methacryloyl chloride (MeOCl) to Tween 20 in the presence of 4-(N,N-dimethylamino) pyridine, using THF as a solvent, in order to investigate their suitability ...

2007

Solidification Behaviour Of PLLA/nHA Nanocomposites

Jan-Anders Edvin Maansson, Pierre-Etienne Bourban, John Christopher Plummer, Claire Diane Delabarde

PLLA crystallization rates increase with nHA content owing to increased nucleation, which compensates a decrease in spherulite growth rate, G, at 100 to 130 °C, and to suppression of the twin peak in G(T) seen in pure PLLA, linked to a transition from the ...

Biodegradable polylactide/hydroxyapatite nanocomposite foam scaffolds for bone tissue engineering applications

Jan-Anders Edvin Maansson, Pierre-Etienne Bourban, John Christopher Plummer, Claire Diane Delabarde

Supercritical carbon dioxide processing of poly--lactide (PLLA)/hydroxyapatite (nHA) nanocomposites was investigated as a means to prepare foams suitable as scaffolds in bone tissue engineering applications. For given foaming parameters, addition of nHA to ...
