The mechanism governing the electrical properties for phase separating blends containing multiwall carbon nanotubes (MWNTs) is unravelled by tuning the compatibilization efficiency. Thereto, compatibilization by interfacially segregated block and random copolymers (cp) of poly(styrene-random/block-methyl methacrylate)(PS-r/b-PMMA) was achieved in phase separating blends of poly[(α-methyl styrene)-co-acrylonitrile]/poly(methylmethacrylate)...
By influencing both the interfacial adhesion and the morphology, compatibilizers determine the mechanical properties of polymer blends. Here, we study the mechanical properties, in particular the fatigue crack propagation (FCP) of immiscible blends of poly(2,6-dimethyl-1,4-phenylene ether)/poly(styrene-co-acrylonitrile) (PPE/SAN), compatibilized with Janus nanoparticles (JPs) and linear polystyrene-block-polybutadiene-block-poly(methyl...
An in situ amide hydrosilylation reaction was developed to prepare polyamide 12 (PA12)/polysiloxane copolymers by reactive blending. This reaction is focused on the addition of hydrogenosilane groups (SiH) from polysiloxane to the carbonyl group from the PA12 amide function. To evidence this carbonyl hydrosilylation onto an amide based polymer, an approach on model compounds (use of N-methylpropionamide)...
This work reports that a partially wet phase can compatibilize and toughen a co-continuous PLA/PA11 blend. Four different polymers: PBS, PBAT, EMA and EMA-GMA are examined for their capacity to partially wet the PLA/PA11 interface in a melt-blending process. All the blends exhibit a partial wetting morphology, but offer very different compatibilization efficacies and toughening effects. EMA-GMA demonstrates...
It is well known that polyolefins, styrene polymers and engineering plastics occupy the largest share of the plastic market and constitute nearly 80% of the world's plastic. However, these plastics are usually used or recycled in mixed state and immiscible with each other. It is hard to define or separate these plastics, respectively, from recycled materials. In this letter, a maleic anhydride (MAH)...
A new formulation of low glass transition temperature phosphate glass (Pglass) was developed to avoid degradation of, then melt blended with poly(ethylene terephthalate), (PET), in the presence of a sulfonated PET copolymer compatibilizer, providing an effective dispersion of the filler in polymer matrix. Compression molded films were then stretched to a draw ratio of 3 × 3 at the polymer glass transition...
