In this paper, a density gradient model is suggested for describing the...
Herein, we propose a new strategy of maskless lithographic approach to fabricate micro/nano-porous structures by phase separation of polystyrene (PS)/Polyethylene glycol (PEG) immiscible polymer blend. Its simple process only involves a spin coating of polymer blend followed by a development with ...

We have studied morphology and kinetics of phase separation and dewetting in thin films of polystyrene and poly(vinyl methylether) blend on glass substrate using light scattering (LS) and optical microscope (OM) techniques as well as using atomicforce microscopy (AFM). As the film thickness ...
Phase Separation Kinetics in Polymer BlendsCoarsening Processes of Phase-separated Structures in Polymer Blends The self-assembling processes via spinodal decomposition (SD) of the A/B blend near the critical composition are classified, at...

Using forward recoil spectrometry and atomic force microscopy, the phase evolution of a critical blend thin film of deuterated poly(methyl methacrylate) (dPMMA) and poly(styrene-ran-acrylonitrile) (SAN) is found to develop by three distinct stages. During the early stage, dPMMA-rich wetting laye...
The manifestation of large number of phase separation is an evidence for the existence of large number of crystalline phases, as established in XRD results. Figure 4 SEM micrograph for (a) PVOZ1, (b) PVOZ2, (c) PVOZ3, (d) PVOZ4 blend samples and (e) EDX spectra for the white ...
