Amphiphilic multi-arm star-block copolymers for encapsulation of fragrance molecules

John Christopher Plummer, Céline Ternat, Harm-Anton Klok

Novel amphiphilic multi-arm star-block copolymers with a hyperbranched core, a hydrophobic inner shell, and a hydrophilic outer shell have been prepared from a commercial hyperbranched polyester macroinitiator by ring-opening polymerization of -caprolacton ...

The morphology of submicronsized core–shell latex particles: An electron microscopy study

John Christopher Plummer, Pierre Stadelmann, Cédric Gaillard

The core–shell structure of a range of acrylic–acrylic latexes has been investigated by combining different specimen preparation methods with transmission electron microscopy (TEM), dark-field scanning transmission electron microscopy (DSTEM) and low-volta ...

Towards Textile-Based Fiber Reinforced Thermoplastic Nanocomposites: Melt Spun Polypropylene-Montmorillonite Nanocomposite Fibers

John Christopher Plummer, Chrystèle Houphouet-Boigny Favre, Martyn Douglas Wakeman

The present work is aimed at assessing the feasibility of integrating thermoplastic polypropylene nanocomposite matrices into conventional fiber-reinforced composites based on hybrid textiles that incorporate both the matrix and glass-fiber yarns, in order ...

Pre- and Post-Transition Behavior of Shear Thickening Fluids in oscillating Shear

Pierre-Etienne Bourban, John Christopher Plummer, Véronique Michaud, Christian Fischer

The dynamic shear-thickening behavior of concentrated colloidal suspensions of fumed silica in polypropylene glycol has been investigated. Dynamic frequency sweeps showed that, for any given solids concentration, the complex viscosity at different imposed ...

Water-soluble, unimolecular containers based on amphiphilic multiarm star block copolymers

John Christopher Plummer, Céline Ternat, Harm-Anton Klok

A new class of water-soluble, amphiphilic star block copolymers with a large number of arms was prepared by sequential atom transfer radical polymerization (ATRP) of n-butyl methacrylate (BMA) and poly-(ethylene glycol) methyl ether methacrylate (PEGMA). A ...

The Influence of Matrix Modification on Fracture Mechanisms in Rubber Toughened Polymethylmethacrylate

John Christopher Plummer, Laure Dupuits Lalande

The fracture behavior of composite rubber particle-toughened polymethylmethacrylate has been investigated over a wide range of test speeds, encompassing impact conditions. When the entanglement density of the matrix was increased and its glass transition t ...

Dynamic Properties of Materials for Alpine Skis

Pierre-Etienne Bourban, John Christopher Plummer, Véronique Michaud, Christian Fischer, Etienne Combaz

The aim of the present research has been to quantify the influence of different materials on the global dynamic response of a ski. The properties of the individual constituent materials were characterized as a function of temperature and frequency using dy ...

Dynamic properties of sandwich structures with integrated shear-thickening fluids

Pierre-Etienne Bourban, John Christopher Plummer, Véronique Michaud, Christian Fischer, Sylvia Aviva Braun

The integration of shear-thickening fluids (STFs) into composite structures has been investigated with the aim of tuning part stiffness and damping capacity under dynamic deformation. Results from oscillatory rheological measurements for a STF based on con ...

Microdeformation mechanisms in rubber toughened PMMA and PMMA-based copolymers

John Christopher Plummer, Laure Dupuits Lalande

The classical method of toughening polymethylmethacrylate (PMMA) is to incorporate composite rubber particles into the homopolymer matrix. This approach has been extended in the present work by (i) combining rubber toughening with chemical modification of ...

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

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 ...
