– We have used quantitative X-ray microscopy in combination with Scanning Force Microscopy to monitor the phase separation of spun cast thin films of polystyrene and poly(methyl methacrylate) blends upon annealing. Both techniques complement and enhance each other in elucidating the complicated structures that develop as a function of annealing time. We have determined the composition of the mi...

in this work, ternary polymer blends based on polypropylene (pp)/ polyethylene terephthalate (pet) /poly(styrene-b (ethylene-co-butylene)-b-styrene) (sebs) triblock copolymer and a reactive maleic anhydride grafted sebs (sebs-g-mah) at various compositions were prepared by co-rotating twin screw extruder. the effects of pet, sebs and sebs-g-mah compatibilizer on morphology of the blends were ex...

The influence of confinement on the steady-state morphology of two different emulsions is investigated. The blends, made from polybutene (PB) in polydimethylsiloxane (PDMS) and polybutadiene (PBD) in PDMS, are sheared between two parallel plates, mostly with a standard gap spacing of 40 microm, in the range of shear rates at which the transition from "bulk" behavior toward "confined" behavior i...

In this study PtFeCo ternary alloys nanoparticles of three dimentional (3D) rhombus shapes dispersed on graphene nanosheets (PtFeCo/Gr) were successfully prepared and studied as electrocatalysts for oxygen reduction reaction (ORR) in polymer-electrolyte fuel cells. A combination of analytical techniques including powder X-ray diffraction, X-ray photoelectron spectra, inductively coupled plasma-...

We recently reported the discovery of soliton-like electrogenerated chemiluminescence (ECL) waves from pure conjugated polymer films and gold-nanoparticles-doped polymer films. In addition to a more detailed study of these polymer systems by changing the film thickness and the distribution of local leaks, we also apply the ECL wave phenomenon to polymer blends of conjugated and nonconjugated po...

The growing need of multifunctional materials with tailor made properties led in the last decades to development novel commercial polymer blends, possessing superior physical respect traditional matrices and showing economical advantages synthesis new plastics. Due progressive increase environmental concerns on management plastic wastes, difficulties sorting technologies limited chemical compat...
