DSCFT

Fig. 2 Comparison of typical lateral scales that are covered in experimental measurements (optical microscopy and SFM) and in a simulation box. DSCFT is sometimes used as an acronym for DDFT. Reprinted from [41], with permission. Copyright 2007 American Chemical Society...

We have now found all necessary equations to numerically calculate the time evolution of the densities in a binary polymer mixture. This leads us to the following procedure which we refer to as the dynamic self consistent field theory (DSCFT) method ... 

Fig. 14 Several density modes displayed on a logarithmic scale versus time. The results were obtained through DSCFT calculations in a three-dimensional system of length Lx=Ly=Lz = 635Re using 7x7x7 functions for a quench from yJV = 0.314 to /JV = 5. The expected exponential behavior during early stages of demixing is well reproduced. From [29]...

Fig. 15 Growth rates obtained through two dimensional DSCFT calculations using local and Rouse dynamics and EPD calculations. The DSCFT results using the pair-correlation function of a homogeneous melt and the EPD results are in good agreement. From [29]...

Fig. 16 Corresponding relaxation rates to Fig. 13. Panel (a) compares the Monte Carlo relaxation rates with DSCFT calculations with local dynamics. Panel (b) compares Monte Carlo results with EPD and DSCFT calculations with Rouse dynamics. For earlier times good agreement in the growth rate is found but Monte Carlo simulations show early deviations from the exponential behavior. From [29]...
