Abstract The effect of a variety of electrolytes on the stabilization and destabilization of the rod‐like superstructures in reconstituted collagen membranes have been studied by small‐angle light scattering (SALE). Structural orders at two levels are effected: association–disassociation at the micron level and the helix‐coil transitions at the mollecular level. In addition to lyotropic salts, several transition metal ions were also studied. They act to disassociate collagen aggregates by the formation of stable complexes.
