Biopolymer foams from Novatein thermoplastic protein and poly(lactic acid)
Novatein is the only commercial thermoplastic protein made from bloodmeal, a highly denatured protein and a readily available by-product of the meat processing industry. One of the major limitations of Novatein is its hydrophilic nature and loss of plasticizer during processing which leads to poor …

Load bearing regenerative repairs for the cartilaginous soft tissue of the intervertebral disc
… hydrogels, low molecular weight acrylated star-copolymers composed of D,L-lactide or trimethylene carbonate with caprolactone were mixed with an aqueous solution of methacrylated glycol chitosan to form a hydrogel-elastomer co-continuous morphology. After photo-cross-linking, the elastomer phase …

High Performance Materials Containing Nitrile Groups
… novolac oligomer was cured with relatively low concentrations of this reagent (~20 wt %) into high Tg (~190 °C) networks. The curing reaction was attrubuted to nucleophilic attack of the phenolic hydroxyl on the nitrile groups of the phthalonitrile resulting in the formation of heterocylic …

Synthesis and Characterization of Multiblock Copolymers for Proton Exchange Membrane Fuel Cells (PEMFC)
… hydrophilic-hydrophobic multiblock copolymers are promising proton exchange membrane (PEM) materials due to their ability to form various morphological structures which enhance transport. Four arylene chlorides monomers (2,5-Dichlorobenzophenone and its derivatives) were first …

Improving Impact Properties of Novatein through Polymer Blending and Reactive Extrusion
… is often used for improving material properties cost effectively. This study aimed to improve the energy absorbing properties of Novatein through manipulating the morphology of blends and assessing the factors that are important during this process; these were, the choice of polymer, composition, …

Linking the Rheological Behavior to the Processing of Thermotropic Liquid Crystalline Polymers in the Super-cooled State
… have attracted great interest because of the combination of their promising properties, which includes high stiffness and strength, excellent processability, and outstanding chemical resistance. TLCPs exhibit inherently low viscosity relative to many other conventional thermoplastics. The low …

Phase morphology and fracture toughness of CNT/polytherimide modified epoxy polymer nanocomposites as matrices for advanced CFPR composites
… advanced carbon fibre reinforced polymer (CFRP) composites. Their relatively high stiffness, strength, glass transition temperature (Tg), and strong bonding to the reinforcing fibres, together with their ease of processing, are attractive attributes. The high crosslink density of cured epoxies, …
