Modelling linear and branched amphiphilic star polymer electrolyte membranes and verification of the bond counting method

摘要: Polymer aggregation at a water content of 16% by volume is modelled dissipative particle dynamics. The polymers contain central hydrophobic bead from which four identical arms sprout out. For type L architectures each arm contains six A and one hydrophilic C whose position varied ([A6−yCAy], 0 ≤ y 6). Each for B two times larger branches with end grafted beads (A12−2y[AyC][AyC], < Type reveal the narrowest pores when are located near middle arm, while they decrease y. Also pairwise unequal linear considered. Among all 19 best connected clusters, derived Monte Carlo tracer calculations through pore networks, obtained architecture short [AC] branches. results explained calculating average number A–A A–C bonds that separated nearest in architecture. These insights might guide network design strategies order to develop alternative polymer electrolyte membranes low percolation thresholds proton diffusion.
