Scattering from multicomponent charged ramified polymeric networks of arbitrary topology

The scattering and critical properties of weakly charged ramified polymeric systems for any arbitrary topology are investigated by using the random phase approximation. The interaction matrix is modeled as the sum of the short-range excluded volume matrix and the long-range Debye–Hûckel matrix. We consider three kinds of systems, namely weakly charged ramified polymers in solution when the scattering behavior is controlled by the presence of the peak that is related to the wave-vector and the system density. For weakly charged ramified polymer blends the same behavior is seen. For the ternary mixture made of two weakly charged ramified polymers immersed in a good solvent, several cases are considered and the scattering behavior depends strongly on the thermodynamic parameter. The critical properties of the systems are also investigated using the stability condition.
