– 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...
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...
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...
