Performance of Chemically Modified TiO2-poly (vinylidene fluoride) DCMD for Nutrient Isolation and Its Antifouling Properties

performance of chemically modified tio2-poly (vinylidene fluoride) dcmd for nutrient isolation and its antifouling properties

the surface properties of tio2-pvdf nanocomposite membranes were investigated by incorporating different chemically modified tio2 nanoparticles into the poly (vinylidene fluoride) (pvdf) matrix. the nanocomposite membranes were prepared via dual coagulation bath diffusion and the induced phase inversion method. the membrane surface morphologies were investigated by using sem and afm and related...

Electromechanical Properties of Poly(vinylidene fluoride- trifluoroethylene) Networks

Random copolymers of 65% vinylidene fluoride and 35% trifluoroethylene were reacted with an organic peroxide, in combination with a free-radical trap, to yield networks of high crosslink density. Crystallization subsequent to the crosslinking yielded ferroelectric materials exhibiting large electrostrictive strains. The magnitude of the electromechanical response increased with an increasing de...

Isothermal Melt Crystallization Kinetic Behavior of Poly (vinylidene fluoride)

Isothermal melt crystallization kinetics of PVDF was investigated by differential scanning calorimetry. Thin PVDF film has been fabricated by the solvent casting technique using dimethylformamide (DMF). Then, the samples were melted and subsequently crystallized in the range of the crystallization temperature (Tc) between 138 and 145 °C. The crystallization kinetics was derived from Avrami equa...

Multiferroic tunnel junctions with poly(vinylidene fluoride)

Density Functional Theory calculations of the ferroelectric poly(vinylidene fluoride- chlorotrifluoroethylene) copolymer, compared to those of poly(vinylidene fluoride)

The quantum mechanics calculations of the energetics and structures corresponding to the different representatives structural conformations of poly(vinylidene fluoridetrifluoroethylene) and poly(vinylidene fluoridechlorotrifluoroethylene) copolymers show that the all-trans, Tp conformation, is energetically stabilized even with a chlorine substituent. The changes in the molecular arrangement as...
