Influence of processing routes on morphology and low strain stiffness of polymer/nanofibrillated cellulose composites

Pierre-Etienne Bourban, Yves Leterrier, John Christopher Plummer, Lars Berglund, Sylvain Cyril Claude Galland

The morphology of polymer/nanofibrillated cellulose (NFC) composite sheets produced using different techniques and its influence on low strain stiffness were assessed by optical and transmission electron microscopy. Solvent processing led to relatively hom ...

Influence of composition on the morphology of polyurethane/acrylic latex particles and adhesive films

John Christopher Plummer, Costantino Creton

Polyurethane (PU)/acrylic hybrid particles with different PU contents were synthesized by miniemulsion polymerization and subsequently dried to give solid adhesive films. The morphologies of the particles and the morphologies and mechanical properties of t ...

Kinetics Of Desorption Of Water, Ethanol, Ethyl Acetate, And Toluene From A Montmorillonite

John Christopher Plummer, Pascal Clausen

Desorption processes of low-molecular-weight compounds from the surface of smectites into the gas phase determine a number of processes, e.g. those involved in drug delivery and the release of herbicides. The desorption has not been investigated thoroughly ...

Influence of molecular architecture on the isothermal time-dependent response of amorphous shape memory polyurethanes

John Christopher Plummer, Charly David Azra, Yaobo Ding

The thermomechanical response of a series of thermally activated shape memory polyurethanes (SMPUs), determined by dynamic mechanical analysis (DMA), has been adjusted by systematic modification of the molecular architecture. It is argued that the free rec ...

Loss of tensile strength in cellulose tissue on the surface of spruce (Picea abies) caused by natural photodegradation and delignification

John Christopher Plummer

Photodegradation of wood leads to discolouration and delignification, inducing damage to the cellular structure. This study is an investigation of the damage and loss of tensile strength of the cellulose fibres in spruce (Picea abies). Microtensile tests i ...

Dynamic mechanical analysis for rapid assessment of the time-dependent recovery behavior of shape memory polymers

John Christopher Plummer, Charly David Azra

Thermally activated shape memory polymers (SMPs) recover from a secondary shape induced by mechanical deformation to a primary equilibrium shape when they are heated to their actuation temperature. In certain applications, for example in the biomedical fie ...
