Fabrication and characterization of co-continuous elastomer-hydrogel composites
… in polymer industry requires new or improved combinations of material properties, which cannot be satisfied by few polymers alone. There has therefore been scientific and industrial interest in mixing two different polymers together to make polymer blends. Of all possible polymer blend …

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 …

Cost-effective processing of immiscible polymer blends into value-added fiber-based products
… for recycling of mixed plastics relies on complex and time-consuming procedures for materials separation or the use of expensive compatibilizers for improving mechanical properties. A simple method for direct reuse of waste plastics without the pre-separation procedure or the compatibilizer …

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 …

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 …

Bijels For Continuous Reactive Separations
… for example a water-soluble catalyst is used in combination with oil-soluble reagents. There are two possible strategies to run these processes. A mutual solvent can be used to promote mixing of the otherwise immiscible molecules; however, such a system would make the separation of the product …

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 …

Polydimethylsiloxane Modification of Segmented Thermoplastic Polyurethanes and Polyureas
… segmented thermoplastic polyurethane with a secondary aminoalkyl functional polydimethylsiloxane (PDMS), which was intended to improve the fire resistance of polyurethane systems. The PDMS oligomer was successfully incorporated into the polyurethane backbone via one step solution …

Synthesis and Characterization of Sulfonated Poly (Arylene Ether Sulfone) Copolymers Via Direct Copolymerization: Candidates for Proton Exchange Membrane Fuel Cells
A designed series of directly copolymerized homo- and disulfonated copolymers containing controlled degrees of pendant sulfonic acid groups have been synthesized via nucleophilic step polymerization. Novel sulfonated poly (arylene ether sulfone) copolymers using 4,4'-bisphenol A, 4,4'-biphenol, …

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, …

The influence of the microstructural shape on the mechanical behaviour of interpenetrating phase composites
… relationship for interpenetrating phase composites (IPCs) is currently poorly understood. In an attempt to improve this understanding this study focused on one particular part of this relationship: the effect of phase shape on the elastic and plastic behaviour. A review of previous …

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 …
