摘要: Investigation of the miscibility between polyethersulfone (PES) and polytetrafluoroethylene (PTFE) will be helpful in preparation functional polymers. The PES PTFE different proportions was studied using molecular dynamics (MD) simulations, Fourier transform infrared spectroscopy (FTIR) scanning electron microscopy (SEM). are partly miscible as weight fraction is less than 30 wt%. interaction polymers cannot chemical bonding, non-bond them play an important role blending. hydrogen bond can ignored due to its low contribution non-bonded energies. Compared with electrostatic interactions, Van der Waals (vdW) shows a large influence on pure PTFE; but PES/PTFE blends decreases increasing addition PES. presence suppresses mobility chains; nevertheless, chains unremarkably influenced by
