Phase separation and surface segregation in 
Co–Au–SrTiO3
 thin films: Self-assembly of bilayered epitaxial nanocolumnar composites

Today, one of the most popular nanomaterials are thin nanofibrous layers, which are used in many fields of industry, eg electronics, optics, filtration and the textile industry. They can be produced by various methods, such as drawing, template synthesis, molecular self-assembly or phase separation method, but the most common method is electrospinning from a solution or melts. Electrospinning is gaining more and more interest due to its versatility, simplicity and economy as well as the possibility of producing fibers from various types of polymeric, ceramic and metalic materials. Nanofibrous layers produced by this method are characterized by high quality and the desired physicochemical properties.

Chemical Pattern

In this work, we have investigated phase separation behavior in PS/PVP polymer blend thin films on gold substrates that have chemical stripes of different periods made by microcontact printing. The influences of pattern period and film thickness have been studied. The experiments have testified that the best result of phase separation, as shown in OM image, was obtained when the period of the chemical pattern is similar to the polymer particle size. Meanwhile, the film thickness plays a significant role on the phase separation. The best pattern replication in the polymer thin films only occurs in a relative narrow thickness range, for example, in this case between 30 and 60 nm. The possible interaction mechanism of the thin polymer film with the underlayed chemical pattern has been discussed.

Polystyrene-b-Polylactide (PS-b-PLA) was dissolved in chlorobenzene, and the development of the micro-phase separation morphology in asymmetric PS-b-PLA thin films was investigated by AFM. The thin films were prepared by spinning casting at the speed of 6000 r/min for 60s on Si substrates. We get different morphologies of PS-b-PLA thin film by changing the annealing temperature from 150 °C to 170 °C. In addition, the annealing time influences the morphology of the film. When the annealing time increased from 2 hours to 15 hours and 30 hours, the morphology transformed from parallel to perpendicular to the substrate. By applying temperature gradients, we can control the morphology and orientation of the Block copolymer film self-assembly.

Cahn Hilliard Equation

In the present paper, the formation of columnar and layered structure during co-deposition of binary thin films is analyzed by kinetic modeling. The kinetic model is based on phase field theory and involves the main processes taking place during binary film growth: adsorption, phase separation, Gibbsian surface segregation, surface and bulk diffusion. The process of phase separation is defined by the Cahn–Hilliard equation, which describes well the kinetics of formation of nanoparticles in binary system with a limited solubility of components. The formation of columns and layers can occur only if other processes such as diffusion and segregation take place. In this paper, the most attention is paid to the formation of multilayered structures during binary components co-deposition, which is experimentally observed, but whose mechanism of formation is not well understood. In the work presented, the mechanism of formation of layers is shown, and the conditions at which this mechanism starts to work are formulated. It is shown that very important aspects are surface segregation of one of the components and depth dependent diffusion.
