In this work, we study the mechanism of kinetically trapping in chemically fueled fibers regulated through transient charge negation. We find that the assembly increases the peptide's apparent pKa, which implies that the molecule remains protonated upon deactivation. In its protonated, uncharged state, the charge-charge repulsion with neighboring deactivated precursors is negligible, which explains why the disassembly is slow, and precursors remain trapped. We believe this mechanism is generalizable for the disassembly of other peptides based on charge-charge repulsion. We also provide solutions to overcome the trapping of the precursor in the fibers, which yield chemically fueled fibers with increased dynamics.
