Drying Induced Phase Separation
Phase separation simulation study related to cellulose acetate-water-acetone has been done. Results show that porous asymmetric and symmetric membranes can be produced by changing the nonsolvent concentration or by the drying conditions without altering the polymer content using dry-casting process. Dry-casting process is the process in which complete evaporation of solvent and nonsolvent takes...
متن کاملMotility-Induced Phase Separation
Self-propelled particles include both self-phoretic synthetic colloids and various micro-organisms. By continually consuming energy, they bypass the laws of equilibrium thermodynamics. These laws enforce the Boltzmann distribution in thermal equilibrium: the steady state is then independent of kinetic parameters. In contrast, self-propelled particles tend to accumulate where they move more slow...
متن کاملFracture phase separation.
Here we report novel phase-separation behavior accompanying mechanical fracture ("fracture phase separation"), which is observed in polymer solutions. Surprisingly, mechanical fracture becomes a dominant coarsening process of the phase separation. The transition from viscoelastic to fracture phase separation corresponds to the "ductile-to-brittle transition" in fracture of materials under shear...
متن کاملEntropic Phase Separation
Any elementary textbook on statistical mechanics will try to convince you that energy is everything w.r.t. phase separation. The goal of this thesis is to show otherwise.
متن کاملInduced Phase Separation
Guide regeneration techniques have been recently used to heal soft and hard tissue defects. In this approach, scaffolding plays an important role. Hydroxypatite (HA) resembles the natural bone mineral and has shown good bone bonding properties. In this work, porous polyurethanes have been prepared by a thermally induced phase separation technique. Freeze drying of the separated polymer/solvent ...
